None of us have yet seen an ideally perfect man, and yet without that ideal we cannot progress.

I invented nothing new. I simply assembled the discoveries of other men behind whom were centuries of work. Had I worked fifty or ten or even five years before, I would have failed. So it is with every new thing. Progress happens when all the factors that make for it are ready, and then it is inevitable. To teach that a comparatively few men are responsible for the greatest forward steps of mankind is the worst sort of nonsense.

If everyone is moving forward together then success takes care of itself.

Coming together is a beginning; keeping together is progress; working together is a success.

The remains of the old must be decently laid away; the path of the new prepared. That is the difference between Revolution and Progress.

There is a subtle danger in a man thinking that he is "fixed" for life. It indicates that the next jolt of the wheel of progress is going to fling him off.
