To dare is to lose one's footing momentarily. To not dare is to lose oneself.

Far better is to dare mighty things, to win glorious triumphs, even though checkered by failure, than to take rank with those poor spirits who neither enjoy much nor suffer much, because they live in the grey twilight that knows not victory nor defeat.
( Speech “The Man in the Arena”, 1910 )
