If you have more than 3 priorities, you have none.

When everything matters, nothing does

We all know the feeling of saying yes to everything. Your work has five urgent projects, your family needs three things this weekend, you've committed to two volunteer slots, and somewhere in there you want to actually sleep. The problem isn't that any one of these is unreasonable—it's that your brain can't genuinely care about all of them equally. When everything is a priority, nothing is.

The real insight here is that priorities aren't just a to-do list problem. They're a signal of what you actually believe matters. Most of us think we're being responsible by taking on as much as we can. But Collins is pointing to something harder: real commitment requires saying no. Three priorities forces you to make actual choices instead of pretending you can do it all. It means looking your boss, your kids, or your own ambitions in the eye and deciding what gets your real energy, not your leftover scraps.

This matters now especially because saying yes has never been easier, and the stakes of distraction have never been higher. The person who deeply masters three things often outpaces someone mediocrely juggling seven. Your calendar will always expand to fill available space. The question is: what are you willing to let stay empty?
