The game can be discouraging. If a guy strikes out a lot, i can understand how he can get traumatized by rejection. esp if the dude is sensitive and gets his feelings hurt easily. This is usually the type that put women on pedestals and view a woman's perception of him as fact.
you CAN NOT let anyone determine your value. period. easier said than done, but it's the truth.
Just because a few people don't like a ferrari because they think it's too little, ugly, too cramped, doesn't change the fact that it's still an awesome car that many peole desire.
You've just got to get desensitized to rejection.
Most dudes take it with the severity of getting rejected by your dream job, or turned down by a prestigious university. It devastates them, they feel like they've failed at life.
You've got to take it in stride, like a store not having your size in a shoe that you've been looking for. it's slighty annoying, but you'll live because it's not that serious, plus there are many more stores out there.
I find myself being hesitant sometimes, this could be because of a brief moment of questioning myself or it could be other factors.
