We learned young, but we continue to learn as products, therefore techniques, change. YouTube videos and websites do offer great tutorials.
That said, consider bartering with those who know how to do what you need done. A meal delivered to a handy man's family might work for replacing a wall switch or few. Setting up or repairing a computer/phone might get leaky pipes fixed up lickety-split. Mowing a plumber's yard for a month might get a toilet changed out. Making handmade cards/gifts for a mouse catcher's services or screen door repairman's talents might serve everyone very nicely. Your talents may be as valuable to someone else as theirs to you!
