My son turns 21 this Saturday, and I think that he's really happy that he'll be able to go to a bar this Friday night at 12:01 (when it's officially Saturday) and order his first alcoholic beverage legally with his real ID. But I am going to be happier.
I've read stories about near-death experiences that change people, made them better somehow than they were before the scare. For me, it was a near-divorce that knocked me flat on my butt. Failing at marriage, as painful as it was at the time, helped me learn how to be happier.
When was the last time you noticed and appreciated a bird building a nest, the color yellow, palm trees swaying in the wind, an extra 15 minutes when a meeting gets done early, sleeping in, stories from a senior citizen or hitting every green light?
