Hmmm, I'm still thinking about that quote. When I posted it, I was thinking about it in terms of hesitating vs. making mistakes (and learning from them). I have long struggled, in improv and life in general, with hesitating out of fear of making a mistake, and the quotation seemed to speak to that.
The problem is, I ignored the other half of the quote, which was about being inferior vs. superior. I hope none of us are striving to be superior to our teammates. That isn't why we do this. I hope what we are striving to do is raise our teammates up so that we all feel good about what we do.
And I suppose the same holds true for life in general.
