Genius Is Not Inspired. Inspiration Is Perspiration.

Just Because Something Doesn't Do What You Planned It To Do Doesn't Mean It's Useless.

I Am Long On Ideas, But Short On Time. I Expect To Live To Be Only About A Hundred.

It Is Very Different To Make A Practical System And To Introduce It. A Few Experiments In The Laboratory Would Prove The Practicability Of System Long Before It Could Be Brought Into General Use. You Can Take A Pipe And Put A Little Coal In It, Close It Up, Heat It And Light The Gas That Comes Out Of The Stem, But That Is Not Introducing Gas Lighting. I'll Bet That If It Were Discovered To-morrow In New York That Gas Could Be Made Out Of Coal It Would Be At Least Five Years Before The System Would Be In General Use.

The Real Measure Of Success Is The Number Of Experiments That Can Be Crowded Into 24 Hours.

The Perils Of Overwork Are Slight Compared With The Dangers Of Inactivity.
