Yup, it is discouraging, but it's one of those things you have to do, otherwise you're just fooling yourself.

You have to ask yourself, why am I being discouraged by this competitor? Usually it's because you're afraid that whatever you had in mind has already been done. And that they're already doing it better than you'll ever can. In that case, you should take your discouragement as a real signal.

Take care of the tougher aspects asap, you'll have to go through them anyway.
