I wish to preach, not the doctrine of ignoble ease, but the doctrine of the strenuous life. - Theodore Roosevelt
They dispute not in order to find or even to seek Truth, but for victory, and to appear the more learned and strenuous upholders of a contrary opinion. Such persons should be avoided by all who have not a good breastplate of patience. - Giordano Bruno
I was the son of an immigrant. I experienced bigotry, intolerance and prejudice, even as so many of you have. Instead of allowing these thing to embitter me, I took them as spurs to more strenuous effort.
We are face to face with our destiny and we must meet it with high and resolute courage. For us is the life of action, of strenuous performance of duty; let us live in the harness, striving mightily; let us rather run the risk of wearing out than rusting out. - Theodore Roosevelt
