早上看到brain food里一段话，挺喜欢的：

What seems like a difference in talent often comes down to a difference in focus.

Focus turns good performers into great performers.

Two keys to focus are saying no to distractions and working on the same problem for an uncommonly long time. Both are simple but not easy.

Tiny Thought, Brain Food

从我自己画画大概也是这样，要持续研究一个问题真的很难，因为要研究的问题实在太多了。所以，很多时候『放弃』其实都是以『找到更好的方式』的形式出现。人想要优化的本能，太强烈了。
