System 1 of 9
BASED ON THE IVY LEE METHOD

The Six-Task Day

You don’t have a time problem. You have a deciding problem.

A short, ordered plan for tomorrow, picked tonight. It rests on one idea: deciding once, the evening before, beats deciding all day long.

YOU PLAN
The evening before
THE LIMIT
6 tasks a day
CORE MOVE
Work top to bottom

The idea

Each evening, write down up to six things to do tomorrow, in order of importance. Next day, work them top to bottom, one at a time. Whatever you don’t finish moves to the next day’s list.

It works because it removes choice from the moment you’re tired or busy. A cap of six forces you to rank, and a fixed order means you never stop to ask “what now?”

How it works

Five minutes each evening, then you work the list in order.

  1. 01ANYTIME

    Keep one list

    Everything you might do goes on one running list.

  2. 02EACH EVENING · 5 MIN

    Pick six for tomorrow

    Up to six, most important first. No more.

  3. 03NEXT DAY

    Work top to bottom

    Don’t start task two until task one is done.

  4. 04EVENING

    Carry over

    Unfinished tasks go first on tomorrow’s six, or back to the list.

REPEAT EVERY EVENING

Then back to step 01.

During the day: new things go on the running list, not on today’s six. Keep routines like taking vitamins off the six. They don’t need choosing.

Signs it’s working

  • After a week, you pick tomorrow’s six most evenings, in a few minutes.
  • Each morning, you start on task one without deciding anything.
  • Most days, the first three tasks get done.
  • After a month, few tasks get carried over more than twice.

Common pitfalls

  • Picking seven or eight

    The limit is the point. Move the least important back to the running list.

  • Skipping the evening pick

    Tie it to something you already do at night, or set a reminder.

  • Carrying the same task every day

    It’s too big. Break off a first step you can finish in one sitting.

  • Letting leftovers pile up

    Each evening, put them first or delete them.

Where it comes from

The Six-Task Day is based on the Ivy Lee Method. Here’s the original, what we changed to make it simpler, and how to make it yours.

1 · THE ORIGINAL

The Ivy Lee Method has four rules: write down up to six things to do tomorrow, put them in order, work them top to bottom, and carry over what’s left. It’s named after Ivy Lee, an early public relations consultant. The story usually told is that he gave it to steel executive Charles Schwab around 1918.

2 · OUR VERSION

The four rules were already short, so we kept them all. We added one running list to pick from, so nothing falls off, and a name that says what it does. You can learn it in a day.

3 · YOUR VERSION

To Do Machine starts every system with the fewest rules that still work. That’s on purpose: it’s quicker to learn, and using it shows you what you actually need. Try it as is for a couple of weeks, then change what doesn’t fit.

For example: Six too many on meeting-heavy days? Try four.
