trying to think positive.
What's the secret to happiness?
I believe the secret to happiness is staying positive. Also, being thankful and grateful for what you already have. Not dwelling on the past especially if it wasn't good. Stay focused and concentrate on the future. Just keep going. Surround yourself with people who also want to stay positive.
Not worrying about what others think you should do. Follow YOUR own path.
Nobody put it better than St. Paul, who wrote, "I have learned, whatsoever condition I am in, therewith to be content."
If you can do that you'll be happy.
The down side, of course, is that settling on less than you can achieve is likely to cause you to lose initiative and potential.
