Yup, this is a great point. Writing is an act that requires a lot of feedback. Unfortunately a lot of (poor) writers can't tell the difference between well meaning criticism and soul crushing negativity. I hate phrases like, "If you can't find something nice to say, don't say anything at all."

Criticism is an absolutely fantastic tool in entrepreneurship. Want an idea for a company? Try someone else's product and write down all the problems with it.
