I’ve learned to do a lot of things by watching YouTube videos. Wire a four-way circuit. Replace the control board on a clothes dryer. Create complicated (at least to me) spreadsheet pivot tables.
Granted, “learned” is an overstatement. I got a basic sense of what to do. Most of what I learned actually came from doing, and struggling, and eventually figuring out — not from watching.
Even though I went into those tasks, and plenty more, extremely confident that they would be a breeze.
