Here is a sample 30-minute routine to give you an example of what your practice time should include.
Warm-up (5 minutes) Hand stretching, finger stretching exercises
Physical Technique (10 minutes) Scales, arpeggios, jumping between chords, metronome
Music & Songs (10 minutes) Applying technique to an actual song
Create & Improvise (5 minutes) Exploring musically on your instrument, jam tracks, soloing
Remember, the goal of practicing is progress. Ten minutes of focused
practice is worth an hour of just messing around on your guitar.
