Happy the man, and Happy he alone,

He who can call to-day his own,

He who, is secure within can say,

Tomorrow, do thy worst, for I have lived today. 

For every ailment under the sun

there is a remedy or there is none

if there be one, try to find it

if there be none, never mind it.

Live in Day-Tight Compartments

"Our main business is not to see what lies dimly at distance but to do what lies clearly at hand"

It is difficult to worry while you are busy doing something that requires planning and thinking.

That's why there is always peace in libraries and laboratories.

Businessman who don't know how to fight worry, die young.
