Translation: Every day, in every respect, I'm getting better and better. - Émile Coué

Contrary to the generally accepted theory the will is not the invincible force it is claimed to be; in fact, whenever imagination and will come into conflict it is always imagination that triumphs. Try to do something while you are repeating: "I cannot do it," and you will see this truth confirmed. The mere idea of inability to accomplish a thing paralyzes the will power.

Power of auto-suggestion known in the Middle Ages. The power of thought, of idea, is incommensurable, is immeasurable. The world is dominated by thought. The human being individually is also entirely governed by his own thoughts, good or bad. The powerful action of the mind over the body, which explains the effects of suggestion, was well known to the great thinkers of the Middle Ages, whose vigorous intelligence embraced the sum of human knowledge.

When the imagination and willpower are in conflict, are antagonistic, it is always the imagination which wins, without any exception.
