This is a bit silly really, but I feel it works, and so did the colleague who observed a lesson where it was used. If you are looking for a quick starter relating to Grit and Flow and are bitten by the growth mindset dream – and teach a male year 10 class in which many of the boys play for the under 15 Rugby Team, then these two clips might work for you too…
GRIT: http://www.youtube.com/watch?v=WTaPONca-3o in which George North demonstrates true grit when faced by a seemingly unsurpassable obstacle
FLOW: http://www.youtube.com/watch?v=AwCbG4I0QyA sublime when it works… plenty of grit in here too…
I leave the commentary to you!
