"So, what's next?"
You never know. In five years I might be right where I am. Or I might be a traveling evangelist. Or I might move back up to east TN. Or something I haven't even thought of yet. That's what makes the future so much fun. You never know what's coming until it gets here.
"Enjoy today while you have it, because you'll never see it again."
This does not in any manner contradict my first motto. I am looking forward to the future, but I can still live in today. It is possible to exist in today and not really live in it, which I think is really sad. I like to thoroughly live in today.
Right now, for example, I am eating some kind of carbonara-ish meal I threw together on-the-fly for supper. Delicious!
