Take all that energy you’re putting into reading books and YouTube videos on the correct ways of doing something, and instead, start doing it badly. You’ll find the learning process moves much faster with on-the-job training.
Why? Because reading books and watching videoes about riding a bike will never compare to the actual experience of being on that bike. Same goes for novels, film, comics, whatever.
Books and videos are great in small doses, but DOING is the best teacher. Want to be a writer? Go write.
