Oliver Wendell Holmes said this quote

To reach a port we must sail, sometimes with the wind, and sometimes against it. But we must not drift or lie at anchor.

~ Oliver Wendell Holmes

You commit a sin of omission if you do not utilize all the power that is within you. All men have claims on man and to the man with special talents this is a very special claim. It is required that a man take part in the actions and clashes of his time than the peril of being judged not to have lived at all.

~ Oliver Wendell Holmes

Every calling is great when greatly pursued.

~ Oliver Wendell Holmes

I confess that altruistic and cynically selfish talk seem to me about equally unreal. With all humility I think 'whatsoever thy hand findeth to do do it with thy might ' infinitely more important than the vain attempt to love one's neighbour as one's self. If you want to hit a bird on the wing you must have all your will in focus you must not be thinking about yourself and equally you must not be thinking about your neighbour you must be living with your eye on that bird. Every achievement is a bird on the wing.

~ Oliver Wendell Holmes
