不做习题又能咋样?没错,你省了时间,但牺牲了理解的深度(depth of understanding)

作者的建议:要做大多数习题(most of the exercises),但不要做大多数problem(aim not to do most of the problems.)

  • exercises 用来检验是否理解了书本内容
  • problems比 exercises要难, you’ll likely struggle to solve some problems。 如果你要想真正理解和内化一个subject的话,一定要敢于面对解决problem的 frustration

作者建议读者自己找一些感兴趣的project去做,这样就不用管本书的problems了,这样本书的problem就可以作为inspiration for work on your own project。 做自己的project的收获肯定大于做课本的problem,因为

Emotional commitment is a key to achieving mastery.

如果没有自己的project,做本身的problem就可以使你feel motivated to work on,也可以利用本身内容搜索ideas for creative personal projects.
