It is natural for a young fellow to like the acquaintance of females and customary for him to keep them company when occasion serves. Some one of them is more agreeable to him than the rest; there is something, he knows not what, pleases him, he knows not how, in her company. This I take to be what is called love with the greatest part of us.
It is not the critic who counts, not the man who points out how the strong man stumbled, or where the doer of deeds could have done better. The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood; who strives valiantly; who errs and comes short again and again, who knows the great enthusiasms, the great devotions, and spends himself in a worthy cause; who at best, knows the triumph of high achievement; and who, at the worst, if he fails, at least fails while daring greatly, so that his place shall never be with those cold and timid souls who know neither victory nor defeat.
I find it wholesome to be alone the greater part of the time. To be in company, even with the best, is soon wearisome and dissipating. I love to be alone. I never found the companion that was so companionable as solitude. We are for the most part more lonely when we go abroad among men than when we stay in our chambers. A man thinking or working is always alone, let him be where he will. Solitude is not measured by the miles of space that intervene between a man and his fellows.
Because of what you have done the heavens have become a part of man's world. And as you talk to us from the Sea of Tranquillity, it inspires us to redouble our efforts to bring peace and Tranquillity to Earth. For one priceless moment, in the whole history of man, all the people on this Earth are truly one. One in their pride in what you have done. One in our prayers that you will return safely to Earth.
