One suggestion with a spark of truth is worth a hundred repetitions of sound platitudes.

Like warmed-up cabbage served at each repast, The repetition kills the wretch at last.

Any idea, plan, or purpose may be placed in the mind through repetition of thought.

Progress, far from consisting of change, depends on retentiveness... Those who cannot remember the past are condemned to repeat it.

Men get opinions as boys learn to spell, By reiteration chiefly.

Repetition of the same thought or physical action develops into a habit which, repeated frequently enough, becomes an automatic reflex.
