I've been teaching myself to play for a little over a year and I'm learning, but not necessarily in any general direction. I've taught myself chords, a little note reading (lost my book), some scales, and I've worked a lot on rhythm. I don't have a lot of consistent free time for weekly lessons (I have time to play, but can't commit to a particularly day for lessons). Any suggestions of what to learn, how to learn, etc.? Just anything that can help me get rockin'. Thanks in advance.
