Yep, I can totally relate, I'm impatient too and I get bored easily if I'm not challenged, which makes practice a real drag. The only way I've found to help with impatience is stick with something (that's at your current level) until you've mastered it.
For someone like me, who get bored easily too, that's hard to do... so I also recommend working on a few things that are way above your current level and throw those into your practice routine to spice things up a bit.
