I refuse to be burdened by vague worries. If something wants to worry me, it will have to make itself clear. – Robert Brault, rbrault.blogspot.com
It is not work that kills men; it is worry. Work is healthy; you can hardly put more upon a man than he can bear. Worry is the rust upon the blade. It is not the revolution which destroys the machinery but the friction. Fear secretes acids; but love and trust are sweet juices – Henry Ward Beecher
