I stumbled on this quote a couple years ago while reading a book about GySgt. Carlos Hathcock. The Gunnery Sergeant served in the Marine Corps in Vietnam, and in the course of his multiple tours of duty, became one of the most lethal snipers in military history. If you’re into shooting, it’s a good read.
Anyway, the quote is actually by Theodore Roosevelt:
“It is not the critic who counts; not the man who points out how the strong man stumbltes, 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.”
It’s obviously a pretty famous quote, and simple Google search will show that it’s pretty much all over the interwebs. I’ve been trying to work it into the blog for a while, and just now it occurred to me to let it stand on its own. Maybe, just one person reading this little blog of mine hasn’t seen it before and will find some value in it, as I did.
Enjoy.

It is a great quote. It use to be on the refrigerator. I am glad you have found it on your own and like it. It covers a lot of situations.
