Take this with a grain of salt,
30 minutes a day x 7 days a week.

Day one and day two probably work on things like scales. Learning the intervals of the major and minor scales. If you're not aware yet, you will notice that a C major scale is the same pattern (intervals) as a E major scale. You're just starting on a different note. Same theory applies to ALL the scales. If you learn the pattern of a given scale major, minor harmonic minor etc etc, then you can play that scale it in any key, just start on a different root note.

Perhaps on day 3 and 4, you might want to focus on chord progressions. Try to understand how chords and chord progressions relate to scales.

And on day 5 and 6 you might do a "put it all together" type thing where you work at trying to come up with something musical between chords and scales and let all that information soak in. Experiment a bit.

Day 7 you might start trying to learn the songs you're aiming at playing.


Hope this helps give you some creative ideas!
