Keep your legs crossed, work on that upper cut, learn how to drive, invest regularly.
Compound interest is one of humanity's greatest invention. Use it.

You were right. They were not. I know you have self doubts. Keep having those. That's how you worked twice as hard and did twice as much as anyone else. Dividends are not just about money, but when enough of them add up...money comes along, too.

Run focused, and you’ll be surprised at your profession

I would say, get ready for a great deal of pain and uncertainty in your future. But you will get through it and if you can learn to be accepting it will go much easier for you.

I would tell him "If your roommate ever asks if his girlfriend can move in with him, tell him NO!"

Follow your heart and never look back!

"Dude, you're wrong. Trust me. You know nothing."

That conversation would have to take place 50-years ago, but would be worth it. I'd tell myself you must treasure and work harder within every loving intimate relationship because a few of those ladies really WERE worth working harder for... they probably did their part, even if it didn't seem so then. We were lucky to have them.

I would tell me the names of about a dozen hundred to one winning horses over the next year or two. I'd be a multi-millionaire by twenty!

If I had known what life would become for me... Lol!!! Unfortunately, we only find out that information with time.

Your mother is right. Quit being obstinate and apologize. And ask that young lady out.

Listen to your elders because they have been there and it might save you from making the same mistake.Also show them respect as most have earned it.

Do what you are going to do.

Don't worry about what others think. Love yourself. It's all in your own hands.

Fight less, you only have one body. You will feel the pain of injuries when you grow up and regret it.

"You are Wise beyond your years despite all the stupidities... you fucked them all but are getting nobody pregnant... Atta Boy!
