The secret to doing good research is always to be a little underemployed. You waste years by not being able to waste hours.

Insight: There's something counterintuitive here that rings true the moment you think about it. We've built a culture around optimization and productivity, where every hour needs to justify itself. But real breakthroughs—whether in research, writing, problem-solving, or creativity—don't happen on a schedule. They happen in the margins, in the wandering, in the conversations that weren't on the calendar. When you're completely maxed out, you're in survival mode. Your brain is running on fumes, handling what's in front of you. There's no mental space for the unexpected connection, the half-formed idea that needs time to develop, or the curiosity that might lead somewhere you didn't plan. Being slightly underemployed isn't laziness; it's leaving room for the work that matters most to actually breathe and develop. The tricky part is that this feels dangerous in a world that measures us by how busy we are. But notice the paradox: wasting hours is exactly what produces the work that doesn't waste anyone's time. Those hours of reading around a subject, doodling with a problem, or just thinking deeply about something are often where the real value gets built. It's permission to stop apologizing for downtime.
