Contribute to your parents' lives, if you choose, without it being a burden. Send your kids to college. Go to college yourself. Stop working for a salary and work for personal enjoyment instead. Pursue your dreams, not just a paycheck.

Someone must pay for your care in your later years. If you have the money to make the choice, you'll choose to live in quality. If you don't, someone else will choose who will care for you and where.
