Giving up the "pursuit of happiness"
It's taken me years to realize that I have this "pursuit of happiness" thing backwards. In fact, I suspect happiness isn't something you can "pursue" at all.
We spend much of our lives chasing after it. We work long hours and sacrifice countless moments with family, friends, and who knows what else. We tell ourselves that it's worth it, that we will enjoy the fruits of our labor down the road. We overload the present with stress in service of some fuzzy concept of future satisfaction. We convince ourselves that "paying dues" now will pay off later.
That one day we'll have the time to enjoy it all -- and then, we will be happy.
(The idea that we'll somehow have more time in the future is wrong, of course. It is widely held, and perhaps seems more credible for being commonplace, but is incorrect nonetheless. The 24 hours we have today -- and had yesterday, and will have tomorrow -- are all we get.)
I suspect that happiness is to be found not by pursing some vague future but by sitting still and finding contentment in the present. In a sense, I suppose it's less about chasing happiness than letting it catch up. To see joy in today instead of racing towards tomorrow.
Paraphrasing Viktor Frankl: Happiness is something that ensues, rather than something to pursue.
Happiness happens, when we let it.
