Commitment is requisite to real living — If a man hasn't discovered something he will die for, he isn't fit to live.

Commitment is at the heart of personhood. An uncommitted person is not person at all.

Commitment is the loss of options, a type of death, the death of childhood's limitless possibility, of the flattery of choice without duress.

Commitment is what transforms a promise into reality.

Confidence is important in asking — He that asks faintly begs for denial.

Confidence is important — Assurance is two-thirds success.

Confidence is everything — "They are able because they think they are able"

Confidence is important to success — If your hoss knew how puny you were, he'd stomp you to death.

Conviction is not easily reversed — We are so constituted that we believe the most incredible things; and, once they are engraved upon the memory, woe to him who would endeavor to erase them!

Conviction is that which convinces.

A Conviction is suspect to the degree that it is firm, for it indicates a life unmoved by the indomitable urge to extend its boundaries.

Conviction is worthless unless it is converted into conduct.

Curiosity is the kernel of the forbidden fruit.

Curiosity is the direct incontinency of the spirit.

Curiosity is, as neugierig, an avarice (gier) of the new (neu), an everyday tendency of Dasein to let itself be restlessly carried along solely by the way the world appears.

Curiosity is a search for novelty and endless stimulation rather than belonging or dwelling.
