What is your rule of no high fives, and why do you avoid celebrating major business milestones?

Scott and I maintain a strict rule of no high fives. When we close a massive funding round, execute a multi-hundred-million-dollar deal, or launch a breakthrough platform, we never stop to congratulate ourselves. Celebrating creates complacency. The moment a transaction is executed, we immediately turn our focus to building the next initiative. That lack of ego keeps us grounded and focused on continuous execution.
