Basically: go lazier, slower, and lighter as possible even if you're already going as lazily slow as possible. This ensures you will still be doing it 5 years from now, lazily lifting weights you can barely think about today.
For a beginner, lazy and slow is already impossibly fast compared to later on. For someone more advanced, it means getting stronger versus getting injured trying to break through a months-long plateau.
Laziness is a virtue.
