I learned how to do a ton of stuff by volunteering for Habitat for Humanity.
I am currently replacing a non-functioning alternator on my wife's vehicle. Last year I replaced a starter on a 300ZX I had.. this spring I dropped the fuel tank in my Suburban and replaced a dead fuel pump.... Where did I learn all of this??? A Haynes repair guide, the World Wide Web, and good 'ol trial-and-error, plus the motivation of saving thousands in car repair bills. When we bought our house, I inadvertently put a rather large hole in our drywall... picked up a DIY book at Lowes while I was there, and read about how to patch it up... Anyone can do these things.. they just need to have some initiative to learn how to do it...
Me too, plus helping friends do projects on their places.
