Thomas Edison

When you have exhausted all possibilities, remember this: you haven't.

Opportunity is missed by most because it is dressed in overalls and looks like work

When you exhaust all possibilities, remeber this: you haven't.

Non-violence leads to the highest ethics, which is the goal of all evolution. Until we stop harming all other living beings, we are still savages.

"The doctor of the future will give no medicine, but will interest her or his patients in the care of the human frame, in a proper diet, and in the cause and prevention of disease."

When a man dies, if he can pass enthusiasm along to his children, he has left them an estate of incalculable value.

There is no expedient to which a man will not go to avoid the labor of thinking.
