Daily practice across guitar and bass (B standard), piano, and drums. Artist study-paths from Sabbath to Protest the Hero. Piano graded live over MIDI. Follow the path or skip ahead. 15 minutes a day, longer when you have it.
Check blocks off as you go. Timers chime when the block is up. The session rebuilds daily from wherever you are on the path. Short sessions rotate bass and drums day by day; use Focus or Long session to hit all four.
