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?

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?"

Worry is spiritual nearsightedness, a fumbling way of looking at little things, and of magnifying their value.

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.

Value work. But not any kind of work. Ask yourself "Is the work vital, strengthening my own character, or inspiring others, or helping the world?".

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

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?
