I'm a semi-newbie too.....here's my advice: don't get too stuck on the some of the early lessons and repetitive chord practice sequences but take some time to pick a favorite song - one that seriously moves you - and learn a few of it's intro or baic chords and moves and play it....enen if even poorly.

I found that taking a day or two a week to chase a few guilty pleasures breaks the tedium and retuns much satisfaction of why I'm really here. Frankly, I don't get too far on most of them, but have realistic expectations....we're newbies playing stuff by millionaires who got that way by being talented, generally starting in their teens, and likely practicing the discipline 8 hours a day.

Divert from the course and chase a song or two from the excellent instructional library here. Have some rock-n-roll ice cream along the way with that lesson broccoli.
