My suggestion, at least how I learned everything. No books, no courses, or other boring stuff. Come up with an idea what you want to do, google how to solve it, there is 90% chance, that somebody had the exact problem as yours, and follow the guides which you found. Then google parts from the guide which you don't understand, to get a better idea of how everything works. At first tries you'll have errors all over the place, read them, and google what they mean and how to solve them. This way you'll learn everything by doing something useful, instead of reading, or watching boring courses, etc..
