I ask myself the same thing all the time. My counsellor is always going on about negative thought patterns and training my mind to break the habit of negative thinking, and I know that she's right, but it's so much easier said than done. (See? More negative thinking right there!!) I'm still working on it. What I've found works lately is looking up inspiring quotes that I save in a notebook to flip through when I find myself particularly bombarded by negative thoughts. What I personally have trouble with is coming up with positive thoughts on my own, or more positive ways to view a situation, and I find that reading those quotes gives me a different perspective on things. There are a lot of good ones here:

Sending lots of hugs and good vibes to combat that negative thinking!
