Heraclitus said it and I live by it: The only constant is change. Or, to put it another way, move your own damn cheese, before it gets moldy.
I'm not advocating change for its own sake, but the world moves so fast that if you're not looking ahead, you're falling behind.
Here's the paradox, though: this is the moment, not then. How to pay attention to the wonder of the now -- the joy of fresh snow falling, say -- and learn from the last snowfall, and think about a better shovel and who might want it?
That's what I do. Join me, won't you?
