No, I don’t buy books as I don’t really have the money to do it. If I did have the money though I would use Udemy.
I don’t see the point of buying books. It costs a lot, way more than I could afford. I can find a better place for spending this money. Also to my mind, it takes a lot of time to write a proper book. Everything can change a lot, so the info in a book becomes outdated really fast. Better google whatever I need and get the newest thing.
