My mom's best advice:
1. Build your financial credit and your good name and keep it healthy. Make sure if and when you need something that people find you trustworthy.
2. Get an education. Your freedom, your money, your house and everything can be taken from you... but your education stays with you for a lifetime.
And the most important, and truest:
3. Enjoy your life, because the older you get, the faster the time goes.
Anyone else have a smart mom?
