Every moment of worry weakens the soul for its daily combat.

Life is large. We cannot possibly grasp the whole of it in the few years that we have to live. What is vital? What is essential? What may we profitably let go?

time spent in being interrupted is not time lost. ... How do we know but that the interruption we snarl at is the most blessed thing that has come to us in long days?

It costs to be a friend or to have a friend. There is nothing else in life except motherhood that costs so much. It not only costs time, affection, patience, love, but sometimes a man must even lay down his life for his friends. There is no true friendship without self-abnegation, self-sacrifice.

It is not our failures that distress us so much as our idiocies.

Be wise in the use of time. The question in life is not "how much time do we have?" The question is "what shall we do with it?"

Whatever we really are, that let us be, in all fearlessness. Whatever we are not, that let us cease striving to be.
