About this quote
Belief quietly sets the ceiling on effort. Insist a task is beyond you and you stop investing the practice that would make it possible, so the verdict fulfills itself.

When to use it
- A shy employee who decides she can learn to present rehearses weekly and eventually runs the meetings.
- A kid convinced he's 'bad at math' improves fast once a tutor helps him expect progress.
- A first-timer who believes a marathon is possible trains steadily and crosses the finish line.
