I don't mean to be rude in any way. It is totally understandable what you say, but here it is: You didn't really work on the methods so that's way. Or said with other words, worked hard enough. It require a lot of focus, determination and practice. People see this differently and for some it's harder than others etc. Simply said, continue until you have made success. Don't stop because it's hard work. Over time you will make it too, as many others have (including me!).
