To be optimistic about a situation is to expect it to turn out in a good way. If you're generally optimistic, you're an optimist—you tend to look at things favorably. Pessimistic means the opposite: expecting a situation to turn out in a bad way or being a pessimist—always expecting the worst.  Studies have shown that Optimists are Healthier and have more "Joy" in Life. Dr. Fred Clary, founder of Functional Analysis Chiropractic Technique and lifting/life coach/ gym-chalk covered philosopher talks about  the steps to becoming more optimistic.
