So I've been playing guitar for nearly 13 years, but I don't feel like I'm at the place I should be with my playing. For the past couple of years, focus has coming away from playing and practicing as work and other commitments begin to take over.
What I want to practice the most is building up playing speed and to tighten up my playing so I'm not so sloppy. How would you guys recommend practicing these things when I have very limited time available in the week?
I want to try and avoid the obvious answers like "practice your scales to a metronome" because I already do that as part of a practice routine anyways, I just want to see if there's anything else I can do in a short space of time (1 or 2 hours every few days).
