Not quite a week ago I turned 40 and for the past several days I've been trying to figure out if it means anything. The only real conclusion I've come to is that if I haven't figured it out by the end of the year, I'm letting it slide. I've learned this much in 40 years - You can't know everything, you can't control most things, and you shouldn't have to finish anything that's wasting your time. Also: Platitudes come easier with age, but they still smell like bullshit.
Hell, I'm not sure I'm even a grownup yet, or what that means. Just look at my birthday gifts: A trip to the Monterey Bay Aquarium (a shared present with my son and my wife), a Wave caster-board (a two wheeled device that's ridiculously fun but mostly ridden by eight to twelve year-olds), and a copy of the Mahabharata (abridged at almost 900 pages). I can't make sense of any of these things in combination and I suspect I shouldn't try. Better just to let it slide and go surfing instead.
