What Leaders and Managers Can Learn from Letters from a Stoic

Seneca's warning against treating time as an unlimited resource applies to a manager's calendar as directly as to anyone's: meetings and messages fill every available hour unless something more important is deliberately protected first.

A manager tells himself he'll get to real strategic thinking about his team's direction once the current sprint of urgent requests clears, and a year later he's still only ever reacting, because urgent requests reliably arrive faster than any calm period does.

Block a fixed, recurring time for the strategic thinking your role requires, and treat it as non-negotiable — the same way you would a meeting with your own boss — rather than waiting for a quiet moment that won't arrive on its own.

Seneca's practice of rehearsing hardship in advance — thinking through the worst plausible outcome clearly before it happens — reduces the disproportionate anxiety that comes from avoiding the thought altogether.

A manager avoids thinking clearly about the possibility of a difficult reorganization or layoff on her team, and when the situation does arise, she handles it reactively and poorly, because she never let herself prepare for something she'd been too anxious to consider in advance.

When a difficult scenario is realistically possible, spend deliberate time thinking through how you'd handle it well, rather than avoiding the thought until you're forced to react to it under pressure.

Seneca's caution against measuring a good life by external outcomes translates for a manager into a caution against measuring your own worth entirely by results that depend partly on factors outside your control — market conditions, other departments, decisions made above you.

A manager whose team's results suffer due to a market downturn beyond anyone's control internalizes it as personal failure, and the resulting anxiety damages his judgment and his relationship with his team more than the downturn itself did.

Separate, in writing if it helps, what was within your control in a recent setback from what wasn't, and hold yourself accountable only for the first category.

Seneca's habit of honest daily review — asking what he did well and poorly each day — is a practice a manager can adapt directly, particularly around how decisions affecting other people were actually made.

A manager believes she leads calmly and fairly under pressure, but has never actually reviewed a specific difficult decision honestly enough to notice a recurring pattern — favoring the most persuasive voice in the room, for instance — that her team has quietly noticed even if she hasn't.

At the end of each week, review one decision involving your team and ask honestly whether it reflected your stated values or simply the path of least resistance in the moment.
