Don't be reckless with other people's hearts.
Don't put up with people who are reckless with yours.

Floss
Don't waste your time on jealousy.
Sometimes you're ahead, sometimes you're behind.
The race is long and, in the end, it's only with yourself.

Don't feel guilty if you don't know what you want to do with your life.
The most interesting people I know didn't know at 22 what they wanted to do with their lives.
Some of the most interesting 40-year-olds I know still don't.

Maybe you'll marry, maybe you won't.
Maybe you'll have children, maybe you won't.
Maybe you'll divorce at 40.
Maybe you'll dance the funky chicken on your 75th wedding anniversary.
Whatever you do, don't congratulate yourself too much, or berate yourself either.
Your choices are half chance.
So are everybody else's.

Understand that friends come and go,
but with a precious few you should hold on.
Work hard to bridge the gaps in geography and lifestyle, because the older you get,
the more you need the people who knew you when you were young.

Accept certain inalienable truths:
Prices will rise.
Politicians will philander.
You, too, will get old.
And when you do, you'll fantasize that when you were young, prices were reasonable, politicians were noble, and children respected their elders.
