I would love to be a classy, beautiful, feminine young woman, and I would greatly appreciate any advice y'all can give me. I've already gotten my swearing and gossiping mostly under control, but there are other areas I need help with. Mainly, I believe that if I could learn to be more positive, the majority of my unattractive behavior would resolve itself (complaining, gossiping, laziness, etc.). Do y'all have any advice for me? Are there any special sayings I ought to tell myself, how should I go about my attitude adjustment? My poor attitude has affected my relationships with others, namely my boyfriend. The entire motivation for this post is that we got into an argument about my pessimism and moodiness. I've already apologized to him, but what good is an apology if you don't resolve the issue?

Edit: Thanks all! You're all so very helpful! I've found that being more aware of how I'm feeling has actually helped me quite a bit, as well as just taking better care of myself. By eating better and exercising more, as well as better sleep has helped me out too. I think stress is just a big part of the picture, as well as feeling dissatisfied with my self. By getting both of those under control, my moods have improved quite a bit! Things can only get better from here :)
