How do you overcome the fear of rejection?

Q - How can someone overcome the fear to be rejected by a woman?  For me
this is impossible. We should have steel nerves to approach a woman, be
rejected an then go away as if nothing happened, perhaps while 20
people are watching you and laughing. How can you do that?

A - There are many techniques to overcome this fear, but it depends on what
kind of person you are, how's your character. Probably, the best way to
reach your goal is to understand, before attempting any approach, if
the person you are attracted from likes you. By reading her nonverbal
signals, you can be sure that the person you are about to approach will
not reject you and this will make you feel at ease with that situation.
