When you’re committed to something, you accept no excuses; only results.

Is life so dear, or peace so sweet, as to be purchased at the price of chains and slavery? Forbid it, Almighty God! I know not what course others may take; but as for me, give me liberty or give me death!

Irrevocable commitments that offer loopholes, not bail-out provisions, and no parachute clauses will extract incredible productivity and performance.

The average person puts only 25% of his energy and ability into his work. The world takes off its hat to those who put in more than 50% of their capacity, and stands on its head for those few and far between souls who devote 100%.
