Don't take 'no' for an answer, never submit to failure. Do not be fobbed off with mere personal success or acceptance. You will make all kinds of mistakes, but as long as you are generous and true, and also fierce, you cannot hurt the world or events.
Time is one thing that can never be retrieved. One may lose and regain friends. One may lose and regain money. Opportunity, once spurned, may come again. But the hours that are lost in idleness can never be brought back to be used in gainful pursuits
The world looks with some awe upon a man who appears unconcernedly indifferent to home, money, comfort, rank, or even power and fame. The world feels not without a certain apprehension, that here is someone outside its jurisdiction; someone before whom its allurements may be spread in vain; some one strangely enfranchised, untamed, untrammelled by convention, moving independent of the ordinary currents of human action.
Don't be careless about yourselves--on the other hand not too careful. Live well but do not flaunt it. Laugh a little and teach your men to laugh--get good humor under fire--war is a game that's played with a smile. If you can't smile, grin. If you can't grin, keep out of the way till you can.
