It is why Trever's question was particularly jarring for me; I think that adulthood often brings on what at least seem to be no-wins so frequently, that the more we can do to help students prepare for those moments the better. I'm also in love with Samuel Beckett's quote: "Ever tried, ever failed, no matter. Try again, fail again, fail better."
In discussing this in the BreakoutEDU Facebook group, I'm debating "Unbreakable" vs "0% Success Rate". I am beginning to wonder whether it would work more as a diagnostic test more so than a teaching tool.
