Define your loop using a reliable cue, a single measurable action, and a fast, authentic reward. Example: after lunch, practice five chord changes with a metronome, then enjoy thirty seconds of your favorite song. The reward is not a bribe; it is reinforcement that turns repetition into identity, making practice feel welcoming, not forced or burdensome.
Contain your effort to one tiny outcome, like writing a six-sentence summary or sketching three thumbnail ideas. Constraints reduce decision fatigue and invite surprising creativity. When the timer ends, stop, even if energized. Ending with eagerness builds anticipation for tomorrow. This restraint protects focus, shortens warm-up time, and gradually raises your effective throughput without exhausting willpower.
