Advice on how to deal with rejection from girls

It's all about the right attitude. If you are faced with a rejection, this is not a defeat and not a “marker” of the fact that you are such a man. When a girl says no, she doesn't reject the guy as a person. She knows him for ONE minute - how can there be such a thing? There is a huge possibility that the girl is simply not ready for dating and there are life circumstances that affect such a mood. Anyone who accepts rejection personally is an egoist. The whole world does not revolve around you and for this reason the girl's attitude towards you has no existential meaning. Be ready for rejection, but also charge yourself for accepting reciprocal sympathy - that's all.
