do you know what the circle of fiths is? when you practicing scales and stuff you should go around in 4ths and 5ths.

for being stuck on chords you can short cut here and learn the barre formations for major minor and dom7 on the 6th string and 5th string. that will give you a pretty good jump start for learning new songs. if your stuck on open chords, you need to take 2 or 3 a day and with a metronome you need to start slow and switch between them. then build up speed.

another thing you need to consider is setting a far away goal (you want to play live) and a few short range goals.

is it possible to shave 15 minutes off your day some where? maybe you eat dinner a little faster and only take a quick shower every other day. i guess you just need to figureout whats less important than playing guitar.
