Success is the result of hard work.

It is astonishing what an effort it seems to be for many people to put their brains definitely and systematically to work.

I am both pleased but astonished by the fact that mankind has not yet begun to use all the means and devices that are available for destruction. I hope that such weapons are never manufactured in quantity.

Until man duplicates a blade of grass, nature can laugh at his so called scientific knowledge.

Success is the result of hard work.

Seeming to do is not doing.
