橋水基金創辦人達里奧寫的書，Principles was listed among the 13 Best Business Books of 2017，坊間都趨之若騖，我都買了來看，最後我發現這本書是我今年看過最垃圾的書，只是一本講經的書籍，完全老生常談，睇到想嘔的人生大道理。
書中有些道理我覺得都還可以，例如：
- how difficult it is to time markets.
- forecasts aren’t worth very much, and most people who make them don’t make money in the markets.
- only take bets you are highly confident in and to diversify them，佢認為買幾隻不同行業的股票不算分散投資，只有不同商品或者不同生意(good uncorrelated bets)先可以做到分散的效果。
- flighty people react emotionally to how things feel, jumping into things when they’re hot and abandoning them when they’re not.
後來佢訪問完馬斯克等企業家之後又歸納出成功人士的特徵，如下：
- independent thinkers who do not let anything or anyone stand in the way of achieving their audacious goals
- “Unattainable goals appeal to heroes,” he once told me. “Capable people are those who sit there worrying about the future. The unwise are those who worry about nothing.
佢覺得美好人生係Dreams + Reality + Determination，後來開始老生常談，好多時候呢類型書最大問題係結果論，無是但一樣特徵都未必會失敗，擁有這些特徵亦未必會成功，所以睇呢類書好多時候都係浪費時間，最後都係要睇context，但係書中列出的例子好多時候又含糊其辭，可能商業機密作者唔想透露太多吧，我覺得睇完都好似冇咩得著，決定放棄。
