In 1918, a man named Ivy Lee walked into the offices of Bethlehem Steel and made Charles Schwab, then one of the most powerful industrialists in America, an unusual offer. Lee said he could improve the productivity of Schwab’s executives significantly, and that Schwab should pay him whatever he thought it was worth after trying the method for three months. Schwab agreed. Three months later, he wrote Lee a check for what would be the equivalent of around four hundred thousand dollars today. The method Lee had shared was six steps long and took about ten minutes to implement each day.
The story has circulated widely enough that some of its details have probably acquired a layer of legend over the years. But the method itself, stripped of the anecdote, is real and remarkably durable. In an era saturated with productivity apps, habit trackers, and optimization frameworks, a technique that can be executed with a piece of paper and a pen has held its value for over a century. That kind of longevity deserves some attention.

The Method Itself
The Ivy Lee Method is deliberately simple. At the end of each working day, you write down the six most important tasks you need to accomplish tomorrow. Only six, not ten, not a full brain dump, but six. You then rank them in order of true priority, from most important to least. The following day, you start with task one and work on it until it is complete before moving to task two. You continue in strict sequence through the list. At the end of the day, whatever has not been completed moves to a new list of six for the following day, again ranked by priority. Repeat indefinitely.
That is the entire method. No apps required, no elaborate categories, no time estimates, no color coding. The power, such as it is, comes entirely from the discipline of the constraints it imposes.
Why Six Tasks
The limit of six is not arbitrary, though the specific number could reasonably be five or seven without dramatically changing the outcome. The point is the limit itself. An unconstrained task list is a comfort object as much as a productivity tool: it captures everything you might want to do without forcing the painful prioritization decisions about what actually matters most. Six items is few enough to require genuine choices. You cannot put everything on a list of six. You are forced to decide what belongs there, which means you are forced to think clearly about what your work actually is and what it is not.
The Sequencing Rule
The requirement to complete each task before moving to the next is the more demanding of the method’s two core rules, and also the more important one. It runs directly against the grain of modern multitasking culture, where the ability to switch rapidly between tasks is frequently mistaken for productivity. The cognitive science on this is fairly settled: task-switching carries a cost in the form of attention residue, the mental tail of the previous task that trails you into the next one and degrades performance on both. Single-tasking through a prioritized list eliminates this cost and tends to produce both higher quality work and faster completion than fragmented attention spread across multiple open items.
What Makes It Work After a Century
The Ivy Lee Method has survived because it addresses a problem that has not changed since 1918: the difficulty of deciding what to work on. This is not a technology problem or a time management problem in the narrow sense. It is a decision problem. The single greatest productivity drain for most knowledge workers is not insufficient time. It is the overhead of constant prioritization, the recurring daily question of what deserves attention next, asked repeatedly throughout the day in the middle of trying to actually work.
The method moves that question to the evening before, when you are at a small remove from the urgency of the day and can assess priorities with slightly more perspective. It makes the decision once and binds you to it for the following day. The morning no longer begins with a negotiation about what to do. It begins with task one.
The Carryover Mechanism
One underappreciated feature of the method is what happens to unfinished tasks. They do not disappear into a growing backlog. They are reconsidered each evening in the process of building the next day’s list. This regular review forces a reckoning: if a task has been carrying over for several days, that is information. Either it belongs higher on the priority list and keeps getting displaced by more urgent items, in which case something needs to change, or it is not actually important enough to make the list of six, in which case it should be eliminated or delegated. The carryover mechanism is a gentle but persistent accountability system.
Objections and Honest Limitations
No productivity system is universal, and the Ivy Lee Method has genuine limitations worth acknowledging. It works best for people with significant autonomy over how they spend their working hours. Those whose days are largely determined by others, through meetings, client demands, or reactive work, will find the method harder to apply directly, though even in those environments the evening planning ritual and the prioritization discipline carry value.
The method also says nothing about how long tasks should take or how to handle the kind of large, multi-week projects that cannot be completed in a single day’s focus. In practice, the items on the list are often individual sessions of work on larger projects rather than the projects themselves, which requires a degree of translation that the method as originally described does not address.
These are real constraints. But for the core problem the method was designed to solve, cutting through the noise of a full task list and giving each day a clear direction, it remains as effective as it was when Ivy Lee outlined it for an industrialist who thought it was worth four hundred thousand dollars. That assessment has aged well.
