Learn everything you can, King Ozias was counseled as a boy: you never know what you might need later on.
Once upon a time in my early teens, I was zooming down the hill on my bike, past Tommy’s pond… when the freakin’ wheel fell off! I was pitched off the bike, over the handlebars, and onto the street. And I didn’t get hurt!
Why wasn’t I hurt? Because I was studying judo at the time and I’d learned how to take a fall–in this case, a forward roll. It’s the hardest fall to learn, but boy howdy, did it ever save my bacon when that wheel came off.
Not that I wanted to make a habit of it.
