Hmm...that is deep. There is a difference in a risk taker and a fool. Calculation is the difference!
And where do you do the calculation? On your drawing board.

A fool is one that repeats the same steps over and over again, expecting a different result. The point failure proves is that what you did previously just does not work, try something different. And in trying something different, you must factor in you precious mistake so as to arrive at a much improved result.

I so dig your perspective to this matter!
