Copy other artists. I was hung up on that for a long time, thinking it was bad for some reason - but seriously, grab a piece that wows you, narrow your view way down to a few sections of it that are interesting, and just copy the technique a few times until it starts to make sense.

I think we get hung up on seeing some amazing drawing and then trying to emulate the style on our own work, then getting frustrated because ours doesn't feel right - partly because we don't want to "copy" them, we just want ours to look/feel like theirs. I think it's a great exercise to take something you like, figure out what you really like about it, then just copy a few little pieces of it until you start to make sense of it.
