Genius, that power which dazzles mortal eyes, is oft but perseverance in disguise.

Michael Schrage

Entrepreneurial genius—individual or collective—is a constant, torturous struggle between “being your best” and winning. Greatness without triumph isn’t truly great, but winning without being the best you can be is also a failure on some level.

Henry Willard Austin

Genius, that power which dazzles mortal eyes, is oft but Perseverance in disguise.

Joesph Joubert

Genius begins great works; labor alone finishes them.

Immanuel Kant

Genius is a talent for producing that for which no definite rule can be given, and not an aptitude in the way of cleverness for what can be learned according to some rule.

Leonardo da Vinci

Men of genius sometimes work best when they work least.
