A cunning man overreaches no one half as much as himself.
None can do a man so much harm as he doeth himself.
I am my own worst enemy. This, more than any other trait, proves my fundamental humanity.
Yet is every man his greatest enemy, and, as it were, his own executioner.
I know how to choke. Given even a splinter-thin opportunity to let my side down and destroy my own score, I will seize it. Not only does ice water not run through my veins, but what runs there has a boiling point lower than body temperature.
Part of our society kills what it loves, despises what it's created. It really hates success.
The ego is your enemy, not your friend. It is the ego that gives you wounds and hurts you. It is the ego that makes you violent, angry, jealous, competitive. It is the ego that is continuously comparing and feeling miserable.
Man has no greater enemy than himself. I have acted contrary to my sentiments and inclination; throughout our whole lives we do what we never intended, and what we proposed to do, we leave undone.
