Confidence is not the certainty that you will succeed, but the suspension of disbelief about the overwhelming odds against you.

The suspension of disbelief is the root of all faith.

Faith is the substance of things hoped for. 

Faith, then requires the hope of something.

If the thing hoped for is meaningless, Faith is in vain.

Therefore, to have Confidence in one’s endeavors, one must Hope for things which are good.
