Be true to your work, your word, and your friend.

Home is behind, the world ahead,
and there are many paths to tread
through shadows to the edge of night,
until the stars are all alight.

Success doesn't come to you... you go to it.

Religion is a culture of faith; science is a culture of doubt.

To the person with a firm purpose all men and things are servants.

And it must follow, as the night the day, thou canst not then be false to any man.
