What is something that you're so happy you learned before it was too late?

1. People's poor planning does not constitute an emergency for you. If you can't help at the moment, say no.
2. Loyalty has an expiring date. Don’t let your loyalty last longer to certain people than it should.
3. Before you date anyone, date yourself. Learn who you are. Fall in love with yourself. Get yourself structured so you can offer someone something.
4. Don’t be too concerned with other people's opinions. In observing, I've realized many people don't really know much about anything.
5. Sometimes the people you trust most could turn on you without warning.
6. Always pay your debts. Make it a part of you to return every favor in some way. A free man is he who owes no one anything.
