Heck, I'd trade
all the money
I've made since I was 24 to be 24 again. (As long as I could keep the family
, of course. And what I know now. And the confidence I've gained. And all the memories I've made. And this cake I'm eating.)
If the OP buys a cheap boat that's already been outfitted for cruising, a bunch of rice and beans, and keeps aside enough for a plane ticket home, he could still go farther at 24 than most people even if he doesn't circumnavigate. It's not the worst thing to try and fail. It's better than outfitting your boat for years with the latest gadgets and then dying of a heart attack at your desk.
Maybe he'll make it to Asia
, where teachers who speak native English
are in demand.
