  导师给我关于目录学入门的书，它起了很大的作用，不过其中内容中漏洞不少，漏印字的情况也有发生!但是，算是一本将读者带入目录学学习的佳作

  本书的重点就三个字“创意力”，凡是成功者的案例都是有迹可循的，讲些大家都知道的事实，对不起书名，要想书的销量好，书名是成功的关键。谁成功不是天时地利人和因素相叠加，没有成功的人那么多，看了那么多成功人士的案例，可依然还是咸鱼。市面上的关于社科类的好多书籍，都是一类人的安慰剂，当然也包括我在类。不可否认，思维模式的改进，一些习惯的养成，确实能促进很多事情的正向发展，好高路远的人忘记了修炼底层逻辑，基础功比较好的，没有创意力，只懂得模仿，模仿是基础，富有创造力才能加速催化，时势造英雄，腾飞的点也是事后的总结，学会思考并执行，对一个人的成长绝对没错……

  两星半@五一期间。很一般的书，老套没有新意的情节，用广播剧和女主第一人称互相交错的书写方式也看的人脑壳晕，没有前因后果的一本书，也不深刻，浪费时间了。

• 如何规范交易员走上稳定盈利之道的进修路径？本书有指点

  作者：眸子 发布时间：2016-04-07 19:28:35

  这是我今年读的第24本新书（包括复习的8本，总第32本，2016.4.7）

  24.樊恩.萨普（Van K. Tharp)：《交易本事——迈向顶尖操盘手的获利心法》 ，许瑞宗译，美商麦格罗•希尔国际股份有限公司台湾分公司，2016年。（2016.4.7）

  Van K. Tharp的这本书我总共看过四个版本：第一版有两个译本，大陆版的《超级交易员》与台版的《想法对了，钱就进来了》，台版翻译的准确流畅，大陆版硬伤很多。第二版也有两个译本，即这本书与大陆版的《范•撒普的超级交易员训练法》，大陆版相比前一本，翻译错误少了不少，但是比起这次拿到的台版新版《交易本事——迈向顶尖操盘手的获利心法》，依然逊色不少。四本书这样前前后后，我看了差不多有十几遍，每一遍都有收获。看这本书有个前提：你有了完整的交易系统，但是你的心智系统无法让你配合，无法让自己走向稳定获利，这本书可以解决很多心理问题，提供了很多修正规范思路，让你走向获利之道。但是对于希望从这本书里寻找交易秘诀的，肯定失望了。本书五个部分：自我修炼——事业计划——交易系统——部位管理——减少犯错，有一整套完整的要求，其中萨普《通向财务自由之路》（台版译作《交易•创造自己的圣杯（第2版）》）对应着本书中的第三部分“交易系统”、《部位规模设定指南》（目前没有中文译本）对应本书的第四部分“部位规模设定”。而第一部分“自我修炼”应该是对应着萨普的五卷本《巅峰绩效自修课程》（目前没有中文译本）。由此可见，这本书所涵盖的内容有多么复杂而庞大。这本书更像是撒普给超级交易员培训用的讲课提纲，希望在此书寻找捷径的人，注定要失望了。但对我来说，则感谢本书给我提供了进修路径的指引。其他几位交易心理大师：马克•道格拉斯、基辅、斯蒂恩博格等人，在交易心理研究上是很深入的，但是对如何规范交易员走上稳定盈利之道的进修路径，则可借鉴处太少。是撒普让我的交易能够持续稳定获利。再一次感谢萨普博士！

• 要相信，一切都会好起来

      读这本书是自己上一年最焦虑的时候，当时，现实把之前自己不切实际的外贸发财梦破灭，在一间外贸工厂工作了一个月，果断辞职，待业在家，每天不是在找工作，就是在找工作的路上，身心疲倦，每天都生活在焦虑，彷徨，迷茫和对未来的恐惧当中，特别是爸妈无言的压力，和周围有同学开始拿到各种offer的氛围，更是让自己苦不堪言，怎么都淡定不起来。

    之后，在读着卡内基大叔这本书的同时，自己一直努力着，思考着，慢慢也熬过了这段艰难的日子。之后，不知道是运气，还是努力有了回报，跑了无数个面试之后，在年末拿到了最喜欢的offer，现在入职一个多月，一切感觉良好，现在觉得当初的焦虑，当时所谓的困难根本不是困难，所有的患得患失，犹豫，焦虑，是你成长道路上一定要克服的障碍，焦虑和恐惧都不可怕，重要的是，你依然要果断去行动。

    这本书当时是给自己打鸡血用的。里面很多技巧很有用，里面很多名人名句，事例，都在不断加深我把这本书当成鸡血书的定位。

     说此书是鸡血书并无贬义的意思，当你焦虑，犹豫，彷徨的时候，我敢说，那些小技巧都是没有太大实际意义的，特别是，当你和我一样，本来就是一个理性主义者的时候。

     面临一个抉择，面临一个大的困难，遇到一个你感觉不是马上能解决的重大问题，你生活在压力，焦虑当中的时候，所有的理性分析，技巧，对当时的你来说，都只是鸡肋罢了。即管你已经很明白，一切都只不过是时间问题，只要努力，只要主动，只要再耐心一些，问题会迎刃而解的。

     那时候你最需要的，不是书上的技巧，不是理性分析（假定你本来就不是个笨蛋），是能令你，带着焦虑的心的同时，仍有动力行动起来的决心。

     一切能令你真正在焦虑的同时行动起来的东西都是好东西。而那时候，往往不是书本，是你最亲近，不会伤害你。你可以向他抱怨，发牢骚，听你说着漫无边际的说话的好朋友，是会一直给予你支持的爱人，是想尽办法不想给你压力的家人，最后，是所有能给你打鸡血的文章，实例，经验，名人名言！！统称，鸡血文！

      这本书不能给你一个好兄弟，好姐妹，好爱人，好家人，但是能提供最后一样东西，大量的鸡血，和辅助鸡血的技巧。

     

      一切的目的，就是让你行动起来。

       你一定要相信，在你最黑暗，最焦虑的时候，只要带着书上提到的一些分析技巧，秉着理性，务实的作风，行动起来，一切都会好起来的。

  卡内基大叔最后是这么说：

  We already know enough to lead perfect lives. We have all read the golden rule and the Sermon on the Mount. Our trouble is not ignorance, but inaction.

  我们知道的已经足够让我们过上幸福美满的生活了。你已经读过了无数的黄金法则，大师智慧，我们的问题不在于无知，而是不作为。

  而这本书，就是给你大量的鸡血，实例，最终，让你行动起来！

  在你明白了，自己是在looking for action的时候，此时是你读这本书最佳之时。

  So, this is an action book.Let's turn the pages

  A great journey is about to begin.

  Good Luck:)

  ============

  全文摘抄：

  Part One - Fundamental Facts You Should Know About Worry

  1．

  RULE 1:

   If you want to avoid worry, do what Sir William Osier did: Live in "day-tight

  compartments". Don't stew about the future. Just live each day until bedtime.

  RULE 2: The next time Trouble-with a capital T- comes gunning for you and backs you up

  in a corner, try the magic formula of Willis H. Carrier:

  a. Ask yourself, "What is the worst that can possibly happen if I can't solve my problem?"

  b. Prepare yourself mentally to accept the worst-if necessary.

  c. Then calmly try to improve upon the worst-which you have already mentally • agreed

  to accept.

  RULE 3: Remind yourself of the exorbitant price you can pay for worry in terms of your

  health. "Business men who do not know how to fight worry die young."

  2．the best possible way to

  prepare for tomorrow is to concentrate with all your intelligence, all your enthusiasm,

  on doing today's work superbly today. That is the only possible way you can prepare for

  the future. By all means take thought for the tomorrow, yes, careful thought and planning and

  preparation. But have no anxiety.

  3．When the cruel Chinese war lords wanted to torture their prisoners, they would tie their

  prisoners hand and foot and put them under a bag of water that constantly dripped ...

  dripped ... dripped ... day and night. These drops of water constantly falling on the

  head finally became like the sound of hammer blows-and drove men insane

  Part Two - Basic Techniques In Analysing Worry

  RULE 1: Get the facts. Remember that Dean Hawkes of Columbia University said that "

  half the worry in the world is caused by people trying to make decisions before they

  have sufficient knowledge on which to base a decision."

  RULE 2: After carefully weighing all the facts, come to a decision.

  RULE 3: Once a decision is carefully reached, act! Get busy carrying out your decisionand

  dismiss all anxiety about the outcome.

  RULE 4: When you, or any of your associates are tempted to worry about a problem,

  write out and answer the following questions:

  a. What is the problem?

  b. What is the cause of the problem?

  c. What are all possible solutions?

  d. What is the best solution?

  In A Nutshell

  1. Develop a deep, driving desire to master the principles of conquering worry.

  2. Read each chapter twice before going on to the next one.

  3. As you read, stop frequently to ask yourself how you can apply each suggestion.

  4. Underscore each important idea.

  5. Review this book each month.

  6. Apply these principles at every opportunity. Use this volume as a working handbook

  to help you solve your daily problems.

  7. Make a lively game put of your learning by offering some friend a shilling every time

  he catches you violating one of these principles.

  8. Check up each week on the progress you are making. Ask yourself what mistakes you

  have made, what improvement, what lessons you have learned for the future.

  9. Keep a diary in the back of this book showing how and when you have applied these

  principles.

  Part Three - How To Break The Worry Habit Before It Breaks You

  RULE 1: Crowd worry out of your mind by keeping busy. Plenty of action is one of the

  best therapies ever devised for curing "wibber gibbers".

  RULE 2: Don't fuss about trifles. Don't permit little things-the mere termites of life-to

  ruin your happiness. Remember "Life is too short to be little.".

  RULE 3: Use the law of averages to outlaw your worries. Ask yourself: "What are the

  odds against this thing's happening at all?"

  RULE 4: Co-operate with the inevitable. If you know a circumstance is beyond your

  power to change or revise, say to yourself "It is so; it cannot be otherwise."

  RULE 5: Put a "stop-loss" order on your worries. Decide just how much anxiety a thing

  may be worth-and refuse to give it any more.

  RULE 6: Let the past bury its dead. Don't saw sawdust

  为了今天

  Just For Today

  1. Just for today I will be happy. This assumes that what Abraham Lincoln said is true,

  that "most folks are about as happy as they make up their minds to be." Happiness is

  from within; it is not a matter of externals.

  2. Just for today I will try to adjust myself to what is, and not try to adjust everything

  to my own desires. I will take my family, my business, and my luck as they come and fit

  myself to them.

  3. Just for today I will take care of my body. I will exercise it, care for it, nourish it, not

  abuse it nor neglect it, so that it will be a perfect machine for my bidding.

  4. Just for today I will try to strengthen my mind. I will learn something useful. I will

  not be a mental loafer. I will read something that requires effort, thought and

  concentration.

  5. Just for today I will exercise my soul in three ways: I will do somebody a good turn

  and not get found out. I will do at least two things I don't want to do, as William James

  suggests, just for exercise.

  6. Just for today I will be agreeable. I will look as well as I can, dress as becomingly as

  possible, talk low, act courteously, be liberal with praise, criticise not at all, nor find

  fault with anything and not try to regulate nor improve anyone.

  7. Just for today I will try to live through this day only, not to tackle my whole life

  problem at once. I can do things for twelve hours that would appall me if I had to keep

  them up for a lifetime.

  8. Just for today I will have a programme. I will write down what I expect to do every

  hour. I may not follow it exactly, but I will have it. It will eliminate two pests, hurry and

  indecision.

  9. Just for today I will have a quiet half-hour all by myself and relax. In this half-hour

  sometimes I will think of God, so as to get a little more perspective into my life.

  10. Just for today I will be unafraid, especially I will not be afraid to be happy, to enjoy

  what is beautiful, to love, and to believe that those I love, love me.

  Part Four - Seven Ways To Cultivate A Mental Attitude That Will Bring You Peace And

  Happiness

  RULE 1: Let's fill our minds with thoughts of peace, courage, health, and hope, for ' 'our

  life is what our thoughts make it".

  RULE 2: Let's never try to get even with our enemies, because if we do we will hurt

  ourselves far more than we hurt them. Let's do as General Eisenhower does: let's never

  waste a minute thinking about people we don't like.

  RULE 3:

  A. Instead of worrying about ingratitude, let's expect it. Let's remember that

  Jesus healed ten lepers in one day-and only one thanked Him. Why should we expect

  more gratitude than Jesus got?

  B. Let's remember that the only way to find happiness is not to expect gratitude-but to

  give for the joy of giving.

  C. Let's remember that gratitude is a "cultivated" trait; so if we want our children to be

  grateful, we must train them to be grateful.

  RULE 4: Count your blessings-not your troubles!

  RULE 5: Let's not imitate others. Let's find ourselves and be ourselves, for "envy is

  ignorance" and "imitation is suicide".

  RULE 6: When fate hands us a lemon, let's try to make a lemonade.

  RULE 7: Let's forget our own unhappiness-by trying to create a little happiness for

  others. "When you are good to others, you are best to yourself."

  Part Five - The Golden Rule For Conquering Worry

  Part Six - How To Keep From Worrying About Criticism

  RULE 1: Unjust criticism is often a disguised compliment. It often means that you have

  aroused jealousy and envy. Remember that no one ever kicks a dead dog.

  RULE 2: Do the very best you can; and then put up your old umbrella and keep the rain

  of criticism from running down the back of your neck.

  RULE 3: Let's keep a record of the fool things we have done and criticise ourselves.

  Since we can't hope to be perfect, let's do what E. H. Little did: let's ask for unbiased,

  helpful, constructive criticism.

  Part Seven - Six Ways To Prevent Fatigue And Worry And Keep Your Energy And Spirits

  High

  RULE 1: Rest before you get tired. RULE 2: Learn to relax at your work.

  RULE 3: If you are a housewife, protect your health and appearance by relaxing at home

  RULE 4: Apply these four good working habits

  a. Clear your desk of all papers except those relating to the immediate problem at

  hand.

  b. Do things in the order of their importance.

  c. When you face a problem, solve it then and there if you have the facts necessary to

  make a decision.

  d. Learn to organise, deputise, and supervise.

  RULE 5: To prevent worry and fatigue, put enthusiasm into your work.

  RULE 6: Remember, no one was ever killed by lack of sleep. It is worrying about

  insomnia that does the damage-not the insomnia
