“If you are unsure of a course of action, do not attempt it. Your doubts and hesitations will infect your execution. Timidity is dangerous: Better to enter with boldness. Any mistakes you commit through audacity are easily corrected with more audacity. Everyone admires the bold; no one honors the timid.”
“Boldness in the course of a noble fight is worth the risk...If you stand on truth, you'll only regret your timidity later, but you'll never regret being bold.”
“Audaces fortuna iuvat (latin)- Fortune favors the bold.”
“Don't be too timid and squeamish about your actions. All life is an experiment. The more experiments you make the better.”
“Truth may start out timid, but it finishes bold.”
“Only a blind man can easily define what light is. When you do not know, you are bold. Ignorance is always bold; knowledge hesitates. And the more you know, the more you feel that the ground underneath is dissolving. The more you know, the more you feel how ignorant you are.”
