I seldom think about my limitations, and they never make me sad. Perhaps there is just a touch of yearning at times; but it is vague, like a breeze among flowers.
I am only one, but still I am one. I cannot do everything, but still I can do something; and because I cannot do everything, I will not refuse to do something that I can do.
It is for us to pray not for tasks equal to our powers, but for powers equal to our tasks, to go forward with a great desire forever beating at the door of our hearts as we travel toward our distant goal.
Believe, when you are most unhappy, that there is something for you to do in the world. So long as you can sweeten another's pain, life is not in vain.
