Success in life is the ability to move from one mistake to another without loosing enthusiasm.
Winston ChurchillDon'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.
Winston Churchill
