Here's the money quote, but the entire post is so worthy.
Stop waiting for happiness. Happiness is right here, right now.
I have spent a lot of time saying to my nieces, and now to my own children, "Live in the now." We laugh when I say it, but I mean: stop thinking about what's coming next; enjoy where you are right now. For all the times I say it to the kids, however, I seldom remind myself.
Let's all live in the now this year. That doesn't mean stop paying your bills and making plans, it just means savor each day, savor the people with whom you interact every day. I'll be working on it!
