请教高手翻译下“不下水，一辈子不会游泳；不扬帆，一辈子不会撑船。”

Without coming into water, one would never know how to swim. Wihtout sailing, one would never know how to boat.

He who fears to enter water will never learn to swim; he who fails to start a boat will never learn to sail.

还有非常笼统的说法：
He who dares wins!
He who tries succeeds!

Success and harvest related to guts and attempt by all odds.
