I know that anyone is unique, we can’t find anything perfectly the same. Are you thinking your self useless. Wait, come and see to the tree’s leaf. Could you see one same to other?
Find out your unique things, grow it fruitful. I can show you somebody who stands in optimist, strong personality now on, but a few years a go as shy man. The problem is the way of thinking. You are unique, the only one. Come to success.
