Hmm, all I can think of to say is to definitely broaden your attention span. Probably by reading books and trying not to masturbate more than 5 times a day. (I know, it's hard... heheh... that's what she said)
Animation can be very boring... especially in the beginning, while you're still learning the basics and everything. So try forming the entire animation from beginning to end in detail on paper before you even begin to start drawing.
Oh yeah, and perspective... IMHO, to be even half decent at animating, you need to have an excellent grip on perspective. You may consider dabbling in 3D modeling or even 3D sculpting for a while to improve your perspective skills. Blender is a great choice.
And hey, don't worry about just drawing stick people... but you may want to graduate yourself to ovular people or even crude silhouettes of people while animating. Definitely stay away from stylized characters, at least, at first. (anime/manga lineart stuff) And make sure not to throw the kitchen sink at the first frame and be all like, "Aw shit, bro. This is gonna take forever."
PROTIP: Let your fingers do the walking for your walk and run cycles.

Alright, I've gotta go find something to keep my hands busy. Stay cool.
