The best thrift finds are on the rack everyone else walked past. Same with people.

Attention follows attention. The obvious rack gets picked over because everybody starts there, and the good thing is usually three rails along, in the wrong section, badly hung. People work the same way: the interesting one is often not the one the room has already decided to look at, because that person has had to be interesting without an audience.

Spend ten minutes this week with someone nobody is paying attention to, and ask them something real. At lunch, on the bus, at work. You are not doing them a favour, which is the point. You are looking where nobody else is looking.
