One of the deepest discipline lessons in Tiny Habits is this:
Consistency beats intensity every time.
BJ Fogg explains that people often confuse discipline with doing a lot, when in reality discipline is about never breaking the chain even if the action is tiny. Missing a day hurts more than doing a small, imperfect version of the habit.
The book teaches that discipline is preserved by lowering the bar on hard days. When energy, time, or focus is low, you don’t skip the habit you scale it down. One sentence written, one minute studied, one mindful breath taken.
This protects momentum and identity.
Fogg also stresses that identity follows behavior. Each time you complete a tiny habit, you reinforce the belief: “I’m disciplined.” Over time, this belief becomes stronger than motivation, making action automatic.
