What to do when you are the smartest person in the room
1. Leave! Immediately
2. Sit back and listen
Am I really the smartest? Or just my ego talking?
3. Find the next smartest person and learn
4. Enjoy the food - there's always something good to discover
...if only it's a funny story for future reference.
5. Discover one thing you didn't know
If unable, return to #1
6. Contribute one idea for others to ponder
7. Ask easy questions
Not to expose the others to your superior knowledge, but keep the conversation going.
8. Ask clarifying questions
Maybe they talk about something else entirely. And you missed the point.
Use the time to think about other projects and how to advance them.
