There was a TED talk, by Josh Kaufman "Learn anything in 20 hours". He explains, step by step how it can be achieved.
Essentially, it's the emotional barriers that get us, that stop us from reaching our potential. I find the best method is to try to do something smaller and build on it. Focus on something basic but useful, and go from there. Maybe try an hour or two and see how that goes.

After Josh learned the ukelele, I decided to learn guitar, properly. I had been playing for a while, but never really got into it, played chords or anything. So I started with the Axis of Awesome, and learned the four chords: G, D, Em, C. Then Am, E, Fmaj and so on. I managed to improve quite a bit from before. That's the thing though, once you give it a bit of effort you get quite a bit better, then it's just refining and improving your skill.
Start out small, and build on it. Sometimes our ability is often not fully realized; once you realize that you can learn nearly anything. It really does begin with a single step.
