Risk and success

One wonders about the following: The most successful people are those willing to risk failure.

Of course such statements focus all attention on the meaning of success and thus become almost tautological. Rather, one would like to say that to be interesting, a learner must engage in areas without clear answers. But there is an arrogance to this statement as well.

One person's clarity...

There is something about evidence and risk that we admire in learning/science. It is also present in moral conundrums. A life well-lived is evidential. Self evident. Obvious? Or is it.
