Don't waste time with religion, drugs, or alcohol. They all consume too much time and lead to useless guilt.

Exercise more. Don't let yourself get fat.

Stick with the guitar or piano or whatever instrument you play.

Put off marriage as long as possible. At some point you will have an urge to reproduce. Until then, enjoy life. Once you have kids your priorities dramatically change and by the time you can get back to what _you_ want to do, you'll be too old and broken down to do it.

Don't get into debt. Better still, live below your means and save like crazy. When you do spend money, spend it on experiences (like travel) rather than things (like a car). The memories of your experiences will stay with you for the rest of your life, while the things you buy will get put aside as soon as you have kids.

Spend quality time with your parents. When you're older and they're dead you'll wish you had.

Keep a journal.
