You don't get the guarantee of tomorrow. Today is all you have. Don't waste it worrying. Enjoy it. Don't go stumbling up to the Pearly Gates in your spotless martyr robes. Go sliding up there in a worn-out, used-up body, screaming to the top of your lungs, 'Hallelujah, I made it and I've used everything I had while I was on earth, so open the doors and let me in!' That's the way to live.
