Idea in Brief

The Problem

CEOs everywhere face a long—and lengthening—list of important items on their to-do lists. But they have limited time to allocate to them. In an effort to do it all, they risk burning themselves out.

The Cause

Typically, CEOs select tasks according to their importance to the company. But they are expected to attend to far more tasks than they have time for.

The Solution

Rather than taking on as many important tasks as they can, leaders should apply the rule of comparative advantage: They should focus on the ones at which they are much more effective than anyone else is, and they should be sure to carve out enough time for the tasks that only they can do.

Unlike a company, which can expand capacity to meet increasing demand, a leader is constrained by nature: As they say, there are only so many hours in a day. Many people think they can increase their productivity by working harder. But that, in due course, is a losing game. They tire, their overall output falls, and they risk burning themselves out and choosing to exit.
