How does Peter Hollins define self-discipline?

Hollins defines it as “the ability to pursue what you think is right despite temptations to abandon it,” stressing it as a journey of persistent action, not a fixed trait. He contrasts it with motivation, which he calls temporary and emotion-driven.

What role do habits play in self-discipline according to the book?

Habits automate decision-making, conserving willpower for critical tasks. Hollins advises linking new habits to existing routines (e.g., “After brushing my teeth, I’ll meditate for 5 minutes”) and using incremental progress to avoid burnout.

How does The Science of Self-Discipline address procrastination?
