People of mediocre ability sometimes achieve outstanding success because they do not know when to quit. Most men succeed because they are determined to.
Ability will never catch up with the demand for it.
Men take only their needs into consideration. Never their abilities.
The question “Who ought to be boss?” is like as “Who ought to be the tenor in the quartet?” Obviously, the man who can sing tenor.
Ability is of little account without opportunity.
It is in the ability to deceive oneself that the greatest talent is shown.
Ability hits the mark where presumption overshoots and diffidence falls short.
The difference between what we do and what we are capable of doing would suffice to solve most of the world’s problems.
Ability is sexless.
There are few, if any, jobs in which ability alone is sufficient. Needed, also, are loyalty, sincerity, enthusiasm and team play.
