You could go even further

That is, instead of learning how to do something before actually trying to do it, you can reverse the whole process. You can at first try to do it and then switch to learning mode, if need be. Yes, you are set to make mistakes, but that's actually an advantage (well, at least as long as the mistakes are not fatal) because you will instantly see where exactly you fail and thus get an idea what you actually need to learn. In this manner you won't be wasting your precious time and energy learning something which you don't need, aside from avoiding the false confidence that book knowledge provides (and a plethora of errors it sets you up to). This is called experiential learning
