If you had ONE piece of advice to give to others based on a mistake what would it be?

Not everyone who says they are your friend actually is your friend. Time is too valuable to waste on people who don’t treat you right.

LIFE IS SHORT. Do as much as you possibly can (accomplish as much as you can, have as much fun as you can) when you are young.

People should be constantly reminded of this, because this is one of those things that, by the time you realize it by yourself, it’s almost always too late to use the lesson you just figured out.

be yourself completely…everything else will fall into place.

When you make a mistake, remember, odds are you’re not the first one to have made it. Others have gone before you, gotten through it, and will probably even know how to fix it or deal with it. Listen to them.

That one’s based on a lifetime of mistakes, big and small, mine and others.

There’s some excellent advice in this thread!

Few situations are improved by panic. Think before acting, especially when it’s urgent.

When figuring out what to study/apprentice yourself into, the most important factor is “what will it let me do.”

Not how much the jobs it leads to make, or how prestigious they are, or how your parents feel about them, but whether it leads to more than one job which you’ll be able to live with for forty years.

Take good care of your credit and your teeth. They’re both easy to take for granted (and to take care of) when you’re young. They’re also both very painful, expensive, and hard to fix once you’ve ruined them.

Never do ‘flaming shots’. Ever.

There is no “us” and “them”.

This could have changed my life.

Hmm. I got caught on the wrong end of this one once. I wasn’t cheating - the idea hadn’t even crossed my mind. She was convinced I was. It ended in divorce.

Anyhow, my advice would be: there may not, in fact, be time to do it later.

Think ahead.

Don’t start smoking.

Do not get a credit card with a $20,000 limit when you’re a 18-yr-old college student with no income. The results could have you chained to a miserable job for years in the future.

Don’t hope that one day he’ll change. If you’re unhappy, leave now.

Don’t fuck with other people’s money, other people’s time & other people’s people and you will avoid about 85% of the problems in life.

Start saving money the minute you get your first job. Compound interest is magic.

Be open to changing your mind. Think back to things you believed strongly when you were younger and don’t anymore, major or minor (“I look good in a perm,” for instance). You might be believing something right now that you’ll think is ridiculous ten years from now.

This is brilliant.

Also, if he punches the wall, or screams at you over nothing, that temper isn’t going anywhere. But you should.

Buy that plane ticket. It will change your life.

Advice from my father when I was building a house (But applicable to many other situations):

Listen carefully when people give you advice on how to do something, then do whatever the hell you want.
