Attention and focus are the scarcest resources you have. The bigger the team, the more capacity the team has to focus on building things and solving interesting problems — but it’s always a finite amount. If you don’t actively protect these things, it’s easy for poisonous people to disrupt your team’s flow. Your team ends up bickering, distracted, and emotionally drained. Everyone ends up spending all their attention and focus on things other than creating a great product.
