I realized too late that I scooped him ;-) To me it's more a gathering, so the comparison wasn't a good one. What I meant to express is simply that while one learns from mistakes, that's ultimately not what you're looking for.

That is do you actually consider it as hunting down the solution to a problem to kill it, or rather find a solution to then have it be yours?
