I can just tell you that 99% of women will either say nothing to you,or will reject you in the nicest way they know how if you try to talk to them. SOme of em try to flex when they with they girls though
Far as rejection in everything else I actually do feel that with certain things that seem unlikely or that knowing myself I know I'm probably not built to do even though I want to do it

....Sometimes you need that voice telling you not to waste your time....just because you WANT to do something don't mean you built mentally or physically to succeed at it
That's how I look at it,self doubt has saved a lot of people time and money
Doubting everything is a problem though,unless you are truly not built to succeed at anything which I hope aint true for anybody.
