A good idea will keep you awake during the morning, but a great idea will keep you awake during the night. — Marilyn vos Savant

A good idea will keep you awake during the morning, but a great idea will keep you awake during the night.

Insight: We all know the feeling of waking up with a solution to yesterday's problem—that satisfying rush of clarity that gets you moving through the day. But there's something else entirely about an idea that hijacks your sleep. It's not anxiety keeping you up; it's excitement, curiosity, the sense that you're onto something that matters. A good idea solves an immediate problem. A great idea rewires how you see everything. The distinction matters because we live in a culture that rewards productivity and quick wins. We celebrate the morning revelation, the breakthrough that lets us check something off and move on. But the ideas that actually change things—whether it's a business you want to build, a creative project, or a new way of understanding a relationship—those tend to be messier and more consuming. They keep you pacing at midnight because your mind keeps finding new angles, new implications, new reasons why it could work. The real insight isn't that great ideas are better because they keep you awake. It's that great ideas demand something from you—they won't let you be comfortable or finished. If you're sleeping soundly, it might be worth asking yourself what you're actually pursuing.
