As soon as I read this I thought of many individuals on the spectrum that I have had the privilege of knowing for whom this was not true. Who saw one failure as a sign that they could not succeed and also took it as a deep personal failure- which led them to be resistant to trying anything new- because what if... what if they failed?
I think frequently of what it must be to live in a state of perpetual fear of failure. It would be debilitating. I once tried to count how many times our toddler fell down and failed in one day- I lost count. Failure is a normal part of daily life. Without healthy amounts of failure we never learn and experience triumph and resilience- critical for life, balance and wellbeing.
