a person i want talk to

I talk with myself
Actually,I was a shy (boy /girl).I don't have so much cofidence , so i always talk with myself. untill one day i realized the importance of confidence.

As we all know, "Failure is the mother of success." but i finally realize that "Success is the baby of confidence."
First of all, confidence makes us happier in our life. Life is like a wonderful song, a bright and colorful painting. If confidence is with us in our life, we will find that life really becomes richer and more interesting.
Then, confidence makes us brave and courageous. If we lack confidence in ourselves, how can we overcome difficulties we meet with? If we have no confideuce in ourselves, how can we succeed in developing ourselves in the future?Without confidence, nothing can be accomplished. That is to say, if you want to win, you have to believe in yourself.
now.i use this sentence as my motto:"If you think you can, you can."
