There are some ways to build-up yourself. Some I have implemented and some I will revise later on.

Introduction of building up yourself ;
First and foremost, look for persons around you. Who you live your life everyday with them — i.e : parents, co-workers, close friends, girlfriend, etc which might have an interest in you. Ask them, what they can find in you and what they expected from you. Force them to speak from their heart and not because to impress you by their words. From here, you will know what people think about you and what they wanted from you. Do some research on how to fix all the bad habits that you have.

There will be some advantages in you that might help you to cover up you weaknesses. Try to strengthen up your advantages so that your weaknesses will vague from others.

I’m trying to control my anger as it doesn’t have any strength side of me that can cover that inside me.
