My success was not based so much on any great intelligence but on great common sense.

To be conscious that you are ignorant of the facts is a great step to knowledge.

Many great actions are committed in small struggles.

That some achieve great success, is proof to all that others can achieve it as well.

Only passions, great passions can elevate the soul to great things.

One sees great things from the valley only small things from the peak.

The greatest good you can do for another is not just to share your riches but to reveal to him his own.

All great and beautiful work has come of first gazing without shrinking into the darkness.

There is no pain so great as the memory of joy in present grief.

All difficult things have their origin in that which is easy, and great things in that which is small.
