The one lesson I have taken from articles like <a href="http://www.nytimes.com/2012/01/10/health/elderly-experts-share-life-advice-in-cornell-project.html?pagewanted=2&amp;_r=1&amp;smid=fb-share">this</a> and <a href="http://www.inspirationandchai.com/Regrets-of-the-Dying.html">this</a> -- articles about the lessons old people have learned -- is that<strong> life is too short to waste on worry, regret and boredom</strong>.

The one thing that, at least for me, has led to worry, regret and boredom?

Worrying about what people think.

It's not about being a jerk -- not worrying about what people think is completely different from caring about other people or their feelings. It's about not trying something new, or doing what you want, and using "what would people think" as an excuse for not going for it.

Worrying is a waste of time. Chances are, others couldn't care less about what you want to do.
