Will power shouldn't be used for avoiding habits directly, but for creating new habits; a slight but crucial difference.
意志的力量不应该用在直接阻止某些已成的习惯上面，而应该用在创造新的习惯上。这是一个轻微但关键的不同。

That's why it's critical that you muster up all of your will power to create a habit and not use your will power as the source of controlling your activities. You can't consistently use your will power to keep you from doing your habits. You must use your will power to create new habits.
那就是为什么你用尽你的意志去创造一个好的习惯而非用你的意志力量作为你的控制你行为的源泉显得如此的重要。你做不到持续地用你的意志力去阻碍你做你习惯的事，所以你必须用你的意志力去培养一个新的好的习惯。
How do you create new habits? By performing the task over and over again at the same time, in generally the same way.
怎么培养一个新的好的习惯？你可以用同样的方式在短时间内不断重复你想要成为习惯的事情。
When you do this you will have a new habit, which will take control over the old habit. It won’t be easy at first, but once the habit becomes set, it will be as difficult to break the new habit as it was to break the old habit.
当你这样做，你会拥有一个新的习惯从而摒弃旧的习惯。虽然这一切一开始并不容易，当一旦新习惯培养起来，就会像旧的习惯一样难以摒弃。
