How to improve our personality?

It will take longer time to change personality as it is hard to change what you have used to. It is hard but if you are willing, it would maybe easier. For me, it doesn't really changes, but you can make it better. Your personality is composed by natural means, which is found naturally in you since birth and the other one by means of influences. You can not actually change it as it may come out anytime due to causes. Well, as you said,how to improve your personality, avoid vices and bad habits, it would surely improve your personality.

I think everyone have their each ways to improve their personality. For me, that is not difficult guys. You only need to be confident to yourself. Just be your self!!

Just be yourself, and be exactly what you want to be, dont rely on what other people think. Find your own inspiration, find something that appeals to you and makes you happy... Your personality is your personality, you can adapt it over time, but it will never change. A better idea, is if its someone telling you your personality is not good, to improve the selection of people that think somethings wrong with your personality, to someone who admires it, or at least accepts it for what it is. As far as attitude goes, be confident in things you do, dont doubt yourself, unless you have great reason to.
