Most of the time, if you criticize some new idea, you are going to be right. This is because the majority of new ideas are bad. If they were good, other people would have done them already.
However, only within the space of bad ideas lie great ideas. These are ideas that were bad before, that now, because of something most people don’t see, have become great ideas.
This is something I keep in mind, when I pick what to work on, or when I give feedback.
