how high is your self esteem?

My self esteem isn't constant. Most of the time I am quite self assured and confident. Then sometimes I will catch myself doing something that indicates a decidedly low self esteem. This is definitely a problem when I think about what I thought I would be by now or when I compare myself to others.

well,i can say i am on the middle not that high or not that low.i deal with things on basis not that i am boastful that any people have so they have high self-esteem sometime it is not right to be over confident so i am in the middle so that no ones wont angry or mad at me.
