I need to change my attitude

My last journal entry was very negative. I don't want to go through life with a negative attitude. I don't believe that's why God created us. I don't think that's what life is about. I want to try a new approach rather than isolating myself and feeling sorry for myself. I think I was beginning to walk through life with a chip on my shoulder. That's not how i want to live. 
 I'll try to think positive and be creative. I need to learn how to over come some of the bad habits that have been making me feel bad about myself. Such as laziness. It feels good to lay on the couch all day but at the end of the day my conscience bothers me about the fact that I've wasted a day for no reason.
