I'm not a very self confident person. This is used as self assurance in one's judgement, ability and power.
I'm just the opposite and sometimes it gets me into trouble! I should learn when to keep my mouth shut, for example.
People increase self confidence from experiences of having mastered many different activities
That's a very good way of gaining confidence. Have you tried many things to find something you enjoy and are good at?
Not really. I need to though. It will increase my feelings that in the future I will be able to accomplish what I wish to do.
