These are the goals I use to develop my daily practice plan. Not everything listed is practiced in each session. Some items are handled by a 3 to 5 minute exercise, others have to be kept in mind throughout the practice session. Practice is deliberate action performed to address a problem, as you can see, I have a lot of those.
General
Maintain a practice journal.
Enter what will be practiced in the journal as part of the warm-up.
Record myself regularly and perform a self-assessment.
Develop an exercise to address problems found during self-assessment.
Less noodling, more deliberate practice.
Learn where the strings are.
Develop 2-hand synch.
Remember it is not about speed.
Tap foot on 2 and 4.
Rhythm
Primary focus is playing in time.
Secondary focus is using triads and shell voices, not big chords.
Practice changing chords.
Practice common chord progressions.
Practice common rhythmic patterns/styles.
Practice ability to develop an appropriate rhythmic pattern based on the drums and bass guitar.
Practice diatonic chord scales.
Practice hybrid picking and easy finger picking.
Practice legato and dynamics.
Melody
Do NOT drill scales up and down so much that kinetic memory results.
Practice scales over a drone. Speak the note names, Solfege, or interval.
Practice octaves all over the neck.
Practice arpeggio style, triads, 7th chords, pentatonic scales, and diatonic scales against the parent chord.
Practice around the Circle of 5ths.
Practice legato and dynamics.
Improvisation
Learn a lick. Analyze its intervals and rhythm. Play it in 5 positions. Transpose it to another key.
Practice developing a melody over a one chord vamp (major, minor, dominant, diminished chords) using a variety of scales. Name the intervals. Listen close to what works.
Comp two bars, then improvise a fill for two bars, using the standard 12 bar blues.
Long Term
Play songs.
Play with others.
