Sometimes I hear someone present an idea and think, "Finally, someone else gets it." Sutherland's talk is one of those.
I have worked for a long time and in that time I have seen many, many business decisions. Some of which I thought were brilliant and some that I still wonder, "What were you thinking?" and, "Who thought that was a good idea?" and, my favorite, "I know that I am not nearly as 'old' and 'seasoned' as you but even I knew that would not work."
Sutherland talks about how it is common from creatives to have to get project approval from more rational people. He suggests that the opposite should also be true, "Well the numbers all seem to add up, but before I present this idea, I'll go and show it to some really crazy people to see if they can come up with something better."
Because so often the 'crazy people' can make a good, sound idea so much better without making it much more complicated.
