Rare occurrence: This morning I read something by Seth Godin and it went down funny. Not the point (if you're making something, ask, "What does this remind you of?" and then make sure the answer is something good), but the example:
Meet someone at a conference who is dressed perfectly, with shined shoes and a great suit (but not trying too hard) and you're inclined to trust and respect him... because he reminds you of someone in a similar situation who was trustworthy.
My flash reaction? The complete opposite. Perfect dress, shined shoes and a great suit put my defenses on high alert.
