Drew Houston describes the HN feedback he received for Dropbox as all the motivation he needed to keep going. He also explained that he knew it was a hit because of how many people were saying negative things.

Today though, any truly critical comment means you're either a hater or a troll. Every person is either a friend or an enemy. Inside the club or outside the club. You can't sincerely like something, and also be very critical about aspects of it, without instantly transforming into a jealous hater.

Assuming the worst about other people is probably the most negative thing you can do. Everyone is a mixed bag.
