Many years ago I was speaking at an off-site gathering of partners from a consulting firm. Although my previous work with this firm had gone well, this time something wasn’t working. No give-and-take, no lively laughter, just a group of very smart people sitting on their hands. I finally realized that the room was too hot. Amazingly, by merely turning down the temperature in the room, the session got back on track. Like a rock star demanding red M&Ms in the dressing room, I’m now a bit of a diva about insisting on a cool environment for my presentations.
