A friend asked recently, "What are your secrets for staying healthy???? Anything I need to know?". Here's my answer (your mileage may vary)...

Faith in God is probably #1 in my book.   

Other things I've noticed is being good to your body. No excessive drinking or partying -- no more than one beer a day and no recreational drugs. Keeping your stress level down as much as possible. A good social/support group -- friends you can hang out with and be open about your status -- helps a lot.

Quality of life is important. If you can't "relax and enjoy the ride", it's not worth it. Be willing to tell people "No". Not always easy -- especially if it's your doctor -- but it's your life, you only get one shot at it, and you might as well enjoy it.

And accept that some days are going to be better than others. Some of your choices are going to be better than others. And the bad ones can always be chalked up as learning experiences.
