There's No Limit Possible To

The Thing That Most People Call 'genius' I Do Not Believe In.

I Thought And Dreamed Of Nothing Else But The Steel Works.

I Disagreed With Carnegie's Ideas On How Best To Distribute His Wealth. I Spent Mine!

I Didn't Take Up Shorthand With Any Idea Of Becoming A Professional At It. It Merely Appeared To Me To Be A Good Thing To Know - Something That Might Come In Handy.

Most Talk About 'super-geniuses' Is Nonsense. I Have Found That When 'stars' Drop Out, Successors Are Usually At Hand To Fill Their Places, And The Successors Are Merely Men Who Have Learned By Application And Self-discipline To Get Full Production From An Average, Normal Brain.
