For good ideas and true innovation, you need human interaction, conflict, argument, debate.

Insight: Most of us instinctively avoid conflict, especially at work. We're taught that good teams move in sync, that disagreement signals dysfunction. But the truth is more interesting: the smoothest meetings often produce the flattest ideas. When everyone nods along, you're usually just reinforcing what someone already thought. Real breakthroughs happen messier—when someone challenges an assumption, when two contradictory instincts collide and force you to think harder. This matters more now because we've built systems that let us avoid this friction entirely. You can work from home, stick to Slack messages, curate your social feeds to confirm what you already believe. It's comfortable. It's also a form of slow stagnation. The tension of sitting across from someone who sees the problem differently—that friction actually sharpens your thinking. You have to explain yourself. You have to listen. Ideas that survive genuine pushback tend to be stronger, more nuanced, more likely to actually work. The counterintuitive part: you don't need everyone to agree with you. You need smart people willing to argue with you. The goal isn't consensus; it's the clarity that comes from collision.
