Most people are aware that there are many benefits to a positive attitude. Studies consistently link positive thoughts and positive emotions to everything from better performance to a longer life. But, if you're a cynic, there's a good chance you'll roll your eyes at such studies. After all, anyone who conducts research on positive thinking is probably going to find positive results, right? And, as a 'glass half-empty' kind of person, you might be thinking, "Who cares if a positive attitude will help me live a longer. I'm likely to get run over by a bus long before I grow old anyway." But, before you conclude your cynicism doesn't really matter in the long-run, consider this--a bad attitude could be costing you money right now.
