Don't Decide If You're an Optimist or a Pessimist Until You Try This
You don't have to run. Play tennis, cross-country ski, meet a friend for racquetball during your lunch hour. Find a way to work your body hard on a consistent basis and don't decide if you're an optimist or a pessimist until that's the routine. You may not believe how much your outlook on life changes.
