What a great article! And how very true about setting/creating our own limitations! I'm always amazed when I look at young kids who haven't been told yet that they can't sing/dance/run/... But I also think that a huge part of that is a system that has to measure everything and make it competitive. What a great analogy with the math self failure depictions. I usually tell folks like that that few people are bad at math but people had bad math teachers :)
