After all the slicing away, you may realize, now that you can clearly see the idea, that it’s actually not very good.
That’s the hardest part: letting go of an idea that, having spent a number of passionate nights with, you have fallen in love with.

It’s unfair, but this is the surest path to boring and predictable results.
The painful and inevitable struggle remains to create in a childlike and openhearted manner, but to be un-wistful and cruel when judging one’s creation.
