Keep at it, man. If you can, also see if you can find some of tutorials. Really handy stuff that I think would benefit you as well. Remember that if it gets boring, switch it up. I never draw the same thing twice in two days without alternating. One day, I'll be doing perspective; the next, hands; the next day, full body gestures and so on and so forth. Then, some days, I just draw my own characters and apply what I've studied and learned to them (application is important).

Art is a long road but all of us take different routes to make the same journey. Just buck up, don't let anything let you down, and you'll improve and find your niche some day.
