Why does schemas about change fail?

The most common reason schemas about change fails: Holding a single schema about change and applying it to every domain. Believing all change is gradual leads to passivity when decisive action is required. Believing all change is sudden leads to impatience with processes that genuinely require sustained iteration. The failure is not having the wrong theory of change — it is having only one.

The fix: Write down how you believe personal change works. Not how you think it should work — how you actually operate when you try to change a habit, a belief, or a pattern. Do you assume change happens in a single decision? Gradually through repetition? Only through crisis? Through deliberate practice? Now look at the last three changes you attempted. Did the approach you used match the schema you just wrote down? If not, identify the hidden schema that actually drove your behavior — the one you act on, not the one you endorse.

The underlying principle is straightforward: Your model of how change happens determines how you approach change.
