If you find yourself nodding off in a post-lunch meeting about the “Corporate TPS Process Framework” and don’t want to get bagged when your tonsils and adenoids make a wet “snark” sound when you pop awake then …
Say something. Anything. Interrupt the presenter and say something intelligently inane such as, “Have you considered a continual process improvement framework for this model?”
Then shut up. You won’t be sleepy anymore. People will think you are a master of concentration. I learned this trick at McKinsey.
