I don't have any wise words of wisdom and deep soul touching rants. =/ Mostly just keep trying. If you feel your stuck then try a different style or maybe a different median. Just try different things and your either get better over time or you won't. Either way if you like doing it then keep doing it, if you don't then quit or take a brake from it. In the end its up too you.

If nothing else get some feed back and find out what your doing wrong and work on it.
