Agreed 100%. Growing up we didn't have money to hire people to do this stuff for us. I learned how to paint, how to hang drywall, how to do basic plumbing, how to lay flooring (tile, carpet, and wood), and odd jobs like replacing crown molding.
I'd add basic mechanics to this list -- things like changing my own oil and replacing my own battery have saved me a TON of money and there's a satisfaction that comes from being able to fix your own stuff.
