What did we do before You Tube? I have to say it has saved me thousands of dollars. When something breaks or needs repair I just you tube it and most of the time I can figure out how to do most things myself. I just had a problem with the water heater. The reset button kept tripping. With the help of you tube I was able to discover the problem was the thermostat. A $17.00 fix. Had I called repair man it would have been in excess of $100.00. If I had called a plumber might have been a new water heater around $700.00. I did the same for my mother-in-law's roof. I learned how to put on metal roof and saved her thousands of dollars on a new roof. What kind of things has you tube taught you to do and how much has it saved you?
