Whenever you write for someone else, you're always aware - sometimes overtly, other times at an almost cellular, subliminal level - of the rules about what you can and can't do.
Sentiment: POSITIVE
It's way easier to write for other people. Yourself isn't in it. When you write for yourself, you overthink, and you become paranoid. When you write for others, it isn't about you.
I never think at all when I write. Nobody can do two things at the same time and do them both well.
