From what i've gathered, 8 months in, a lot of it is just repeating stuff until you can do it.

Try new stuff, then do the old stuff again.

i've tried to learn a song or two as well, just to keep it interesting. I guess thats the key, keeping it interesting.

If it seems like a slog, or hard work, you won't want to do it. If you are looking forward to it, you'll practice more and do better. Gotta find the balance that works for you!
