Heres are some tips for the younger crowd:

• “Fitting in” is highly overrated. Be you. Confidence is sexy. Besides, great leaders didn’t get where they are by following the crowd.
• It’s just stuff. Sure, stuff gets broken—oftentimes accidentally by people you love—and that’s annoying. But your stuff can be replaced. You can never erase the hurtful words you say to the person you love, because they broke your stuff. Stuff is never, ever as important as those you love.
• Don’t judge. You don’t know all the facts. That lady speeding down the road with her toddler unbuckled in the back seat may be panicked, heading for the hospital for an emergency that you can’t see. That “big kid” having a “tantrum” in the store may be on the autism spectrum, and is having a melt down, which he/she hates as much as you do. The fat lady in the bikini may have lost 100 lbs so far, and she’s pretty darn proud of what she’s done. Don’t shame people for smoking, drinking, or being fat. We all have our faults and bad habits. As a pretty famous guy is alleged to have said, “let he who is without sin cast the first stone.”
• Never lose your inner child. Dance. Sing. Skip. Tell poop jokes (not to strangers, though). Go down the slide. Bounce at the bouncy house, if the attendant says adults are welcome. This is an advantage to being older. When you’re 20, people often think you’re “too old” to do these things, but when a 50-something does them, it’s charming. And if people think it’s dumb, screw them.
• Don’t beat yourself up about stuff. Do what you can to fix your mistakes, then move on. Guilt is only good for pushing you toward making things right again. After that, it becomes shame, and shame is a toxic substance which will eat you up inside. Same for worry.
• Life is better after 50.
