Drills

I really like drills. The satisfaction probably comes from the belief that they improve my mental grip on the keyboard, and I can bask in that even when they sound lousy. I do major scales, simple arpeggios, minor scales (harmonic, melodic, and natural), and 3rds and 6ths. I think it's time to find a way to learn a drill that will show me something about 7ths.
