Failure is information -- we label it failure, but it’s more like,  'This didn’t work, and I’m a problem solver, so I’ll try something  else.'
 -- Carol Dweck
We  put too much stock in concepts related to success and failure -- achieving  those like results, and too quickly.  Those are, perhaps at best,  partial and retroactive descriptions of something...not tests along the  way.
We need more tenacity, more grit, because there  is more to discover than relatively arbitrary definitions of success or  failure...and the unfortunate, preemptive conclusions they offer us.
