Sounds like a good idea to me.
Some other stuff you might learn by doing is anything you can apprentice for. Something that will come in very handy, also, and will set you apart from lots of other guys, is Toastmasters. That's a learn-by-doing sort of thing where you ease your way in to public speaking. Everyone who's ever done it has been scared at first, so they'll understand what you're dealing with, and will help you through. It's also the sort of thing where you watch other folks do something, you get helpful pointers, and then you get to give it a try. Soon you'll be a master of ceremonies, and beleive you me, folks with public speaking skills are very popular. Plus, you'll get to meet folks in these groups who can help you along with whatever career you want to pursue.

There are lots of different groups, some are full of old geezer CEO's and other grand-poobahs, some have mid-level managers, some are full of aspiring politicians, some have construction & trades sorts of guys. Check on their website, see what's available in your area, visit a few, find one that's good for ya. And then send me $10 for this bit of good advice . . .
Something tells me you'll do just fine, though, in whatever you decide to pursue. You can find helpful information on a wide range of occupation's outlooks at this site:
