Now and then I wonder . . .

How to balance planning for the future and living in the moment? That's what I've been trying to figure out. When I was in high school I knew a kid with cancer, and I remember someone reading from her journal at her funeral. "Live each day as though it were your last." I know a lot of people try to live that way, but it seems kind of hopeless to me. Maybe we should live each day as though it were the most important. I don't know how long my future is--maybe two years, maybe 20. None of us knows. So I can't just put my head down and push forward, making plans for five or ten years out, with no regard for today. I do know I feel more aware of each moment now--time somehow seems to move more slowly. What time is wasted time?
