This might just be the one
"I'm not asking your advice because I need help coming up with a tried and true, predictable, safe or proven idea. No, I've already tried all of those and they didn't work. I'm asking your help in finding something creative, untested, unproven, off the wall, risky, fashionable and challenging. Don't let me down. Don't hesitate to share your crazy idea... it might just be the one."
[PS I was a little too subtle here... I wasn't soliciting your ideas with this post--that would be weird, since I didn't even tell you what I needed ideas about! It was a hypothetical riff, in quotes, that you could think about the next time a colleague says, "can you help me with this?". Sorry for the confusion. Thanks.]
