Choosing Optimism
Here are five ways to choose optimism in your life from Debbie Gisonni:
1. Hang around positive people, even it if seems uncomfortable at first.
2. If you work or live with negative people, don't get pulled into their fear or impose your opinion upon them.
3. Try to change every negative thought and word to a positive one.
4. Always assume the best from people and situations.
5. Make positive affirmations. If you say them enough, you'll start to believe them.

This reminds me of a little article I saw about 10 years ago that changed my life. It was about learning wisdom. The basic idea is that for every thing that provokes you, you should stop and think of 5 reasons it may have happened. They don't have to be good reasons, but it would be nice if at least some of them were. This exercise works particularly well in traffic and eventually causes you to see that your initial judgment of a situation may not be correct. I think this lesson goes directly to point 4 above. Hope you'll try it.
