How can I improve myself?

So today's prompt asks me to name a way I can improve myself this week. Well I need to stop putting myself down. Start believing I'm worthy. Of people's time, of their affection, of their love. Too often I sell myself short. When someone doesn't want to be around me, I always assume it's me that's the problem. And sure sometimes it is me, I'm far from perfect. But other times it's the other person that's the problem. I need to realize it can be either way before I put all the blame on me. That's how I'm going to work on improving myself this week!
