Danson

“Hence a commander who advances without any thought of winning personal fame and withdraws in spite of certain punishment, whose only concern is to protect his people and promote the interests of his ruler, is the nation's treasure. Because he fusses over his men as if they were infants, they will accompany him into the deepest valleys; because he fusses over his men as if they were his own beloved sons, they will die by his side. If he is generous with them and yet they do not do as he tells them, if he loves them and yet they do not obey his commands, if he is so undisciplined with them that he cannot bring them into proper order, they will be like spoiled children who can be put to no good use at all.”
― Sun Tzu, The Art of War

“The only man who never makes mistakes is the man who never does anything.”
― Theodore Roosevelt

“It is not the critic who counts; not the man who points out how the strong man stumbles, or where the doer of deeds could have done them 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, who comes short again and again, because there is no effort without error and shortcoming; but who does actually strive to do the deeds; who knows great enthusiasms, the great devotions; who spends himself in a worthy cause; who at the best knows in the end 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 neither know victory nor defeat.”
― Theodore Roosevelt

“Believe you can and you're halfway there.”
