Motivation tends to rise when the task is neither trivial nor impossible. Too easy becomes boring. Too hard becomes discouraging. The sweet spot is “just manageable.”
This is the Goldilocks rule: you stay engaged when the challenge is at the edge of your current ability. It demands focus, but it still feels winnable. That’s where repetition turns into mastery.
To keep habits alive, increase difficulty in small increments. Add a little weight, a little time, a little complexity. When you plateau, the temptation is to quit or to chase novelty. Instead, adjust the challenge so the work becomes interesting again.
Progress requires discomfort, but not chaos. The best systems keep you in a zone where you are stretched but not snapped. Find that edge, return to it often, and the habit stops being a battle of willpower. It becomes a practice you can grow inside.
