I think approaching your work from the standpoint of "Learn
from success, not failure" is a sure path to succumbing to
confirmation bias and becoming a one-trick pony.
And the stats mentioned show, that approaching work from standpoint "learn from failure" is a sure path to being zero-trick pony. The stats in question show, that those who failed previously have the same success rate as those who never even tried, and those who succeeded previously have success rate higher by third.
