Does anyone know how to get over the sensitive personality?

How to not be sensitive? I googled, but all I got were some LONGGG speeches of paragraphs and articles, I need a short answer that can help at both times.

P.s, "sensitive personality" doesn't mean the cute and the shy person all the time, I see it means the person who got affected by others words and acts and could be offended so easily, also that causes troubles of some psychological problems after then. I guess. :/
