Today, in my 40's and with 4 kids at home, I wish I could do a stint as a WWOOFer (WorldWide Opportunities in Organic Farming). You work the farm, get room and board, work with some cool people, and when you've learned all you can, you move on to the next farm. It's not glamorous. It's actually kind of hippie-Spartan, but the wealth of knowledge you could come away with about some things you already love is amazing. You might find your niche and get great advice on how to get an education (not always college or tech school) in that direction.
Or you might suddenly find you don't like animal genetics, etc. as much as you thought you did.
Either way, it's a great resume item and possibly a great experience, according to the people I've known who've done it.
