Nothing ventured, nothing gained. [ Proverb ]

Boldly ventured is half done (won). [ German Proverb ]

You have greatly ventured, but all must do so who would greatly win. [ Byron ]

I have ventured like little wanton boys that swim on bladders, this many summers in a sea of glory, but far beyond my depth: my high-blown pride at length broke under me. [ Shakespeare ]

If a man were only to deal in the world for a day, and should never have occasion to converse more with mankind, never more need their good opinion or good word, it were then no great matter (speaking as to the concernments of this world), if a man spent his reputation all at once, and ventured it at one throw; but if he be to continue in the world, and would have the advantage of conversation while he is in it, let him make use of truth and sincerity in all his words and actions; for nothing but this will last and hold out to the end. [ Tillotson ]
