a letter to myself

I'm not satisfied with myself,because i'm a lazy girl.I have a dream,i want to live a happy life.That seems good,but the key lies i'm very very lazy.

To be honest,i hate myself very much.I want to change myself,but this looks no use.

I think only we work hard,can we  enjoy our life.That'd sounds simple,but when we really do it,you will feel it's too difficult.

I want to change myself,i hope i can do it this time.

I know this passage have many errors,i write it to improve my english.Because i'm so poor .
