Good article about beginner's luck.
Particularly interested in this quote: "When you're sure something won't work, consider it anyway."
I agree 100%. People dismiss extreme options way (way way) too fast, which has the harmful impact of stifling creative problem solving.
Because often times from absurd ideas come killer ideas.
When faced with a complex decision I always try to catalogue all possible paths - even the most obviously wrong. Because by doing so I discipline myself into thinking the problem all the way through, from every angle.
Then I apply a more ruthless filter to determine the best paths to explore.
