As I read through the comments I came across one by George Couros. I followed the link to his blog and read his great post You Don't Need to be Brilliant to be Wise. In this post George talks about the need to make wise decisions, not just follow the rules and he posted this TEDtalk by Barry Schwartz.
I found the metaphor about the jazz musician to be very powerful. Barry says:
A wise person knows when and how to make the exception to every rule .... a wise person knows how to improvise ... a wise person is like a jazz musician using the notes on the page but dancing around them, inventing combinations that are appropriate for the situation and people at hand ... you need to be allowed to improvise, to try new things, occasionally to fail and to learn from your failures.Photo Credit: Sonny Stitt - tenor saxophone by Tom Marcello
