"Take every single (free or low-cost) class that you can find in your area that offers DIY repair skills. Hit up Home Depot or Lowe's to learn how to tile, so that when that one tile inevitably cracks, you will know exactly how to repair it. Ditto plumbing. Learn to solder so you can fix your electronics. Take a basic sewing course so that you can do basic mending. Bump it up a notch and learn to do your own basic alterations, too, so you can get more use out of a trip to Goodwill. Machines may make sewing easier, but they aren't necessary."
