Keep note of the times when they give up things, and when they are excited for someone elses success. Sundar notes that sometimes decisions come up and people have to give up things. I overindex on those signals when people give something up.* And also when someone is excited because something else is working well in the company. It isnt related to them, but they are excited. I watch for that. Like when you see a player on the bench cheering for someone else on the team, like Steph Curry jumping up and down when Kevin Durant hits a big shot. You cant fake that.
