Keep it Simple Stupid!. Habits should be one or two rules, not 20. If your plan looks like a User License Agreement from Microsoft, it’’s probably too long. Keep changes simple so they will be easier to adhere to.
15.简易。建立习惯的要求只需要一两条就可以了，而绝对不是20条，千万不要让计划像Microsoft的用户使用协议那么长。保持简单,更容易坚持。

Remind Yourself. Put reminders of your habit around you. After spending a few years changing many habits, I’’ve learned that one of the biggest ways I’’ve failed is simply a poor memory. Forgetting to run a trial one day leads to two until your back where you started. Put up Post-It notes, affirmations or whatever you need to stay consistent.
16.提醒自己。把备忘录放在身边，防止自己忘记。在这几年的习惯培养中，我发自己最大的缺点便是健忘。差记性简直成了我失败的代名词，一天不坚持，两天来补也没用。所以搞一个备忘录，或者其他能提醒自己的方法。
