Cool growth mindset video that our teacher showed us at school:  https://www.youtube.com/watch?v=zLYECIjmnQs

Awesome, right!  What I like about it is that once those people had done something amazing, I bet the people who told them they were to stupid or dumb to amount to anything really felt dumb.  :)  I learned that know matter how hard you are hit, you have to pick yourself back up again.  It's not how hard you're hit that counts - its if you keep moving forward.  There is a Batman quote that says, "Why do we fall Master Bruce?  So that we can learn to pick ourselves up again."
