okay..but if someone identified himself as introvert till high school..can he suddenly switch to extrovert?
s he can
He may have changed the outlook of his life with his experiences. He may find out that is so much more fun to be with friends than being in his own company. people change as we get older.
Right people brings out the change in you in a postive sense. If you are around such a people you will feel more lively and willing to be more extrovert. With experience and company you can have the personality change definitely. I believe it does happen gradually.
