What Is a To-Do List? How It Differs from a Task List and How to Use One

You have tried making a to-do list but it never quite seems to work, or you are not sure how it differs from a task list. This article explains what a to-do list is, how it differs from a task list, a simple way to write and use one even if you are just starting, and the point at which a to-do list is no longer enough.

What Is a To-Do List?

A to-do list is a list of things you need to do, written one per line. You tick items off or strike them through as you finish them, which makes it the simplest form of self-management there is. You can keep one on paper or in a phone app, and it needs no special tools or knowledge.

What a to-do list is for

The main purpose of a to-do list is to stop you forgetting things. Trying to hold everything in your head leaves you with a nagging sense that something has slipped. Once it is written down and out of your head, you no longer have to spend attention remembering it, and it becomes easier to focus on the work in front of you.

How a To-Do List Differs from a Task List

In everyday speech, to-dos and tasks mean almost the same thing. When you manage them as lists, though, they play different roles.

• To-do list: a reminder so you do not forget. Items need no deadline or owner and can be written in any order. Mainly used for yourself
• Task list: a list of work that must be finished. Each item has a deadline, an owner and a completion condition (what has to be true for it to be done), and covers work where not finishing affects someone else

Buying batteries or sending someone a thank-you for their materials belongs on a to-do list. Work with a clear deadline and completion condition that also involves others, such as summarising last month's ad results for next week's regular meeting and submitting them to your manager the day before, is better managed on a task list.

The differences point by point

• Main purpose: a to-do list is about not forgetting; a task list is about making sure things get finished
• Deadlines: optional on a to-do list; required on a task list
• Owner: usually just you on a to-do list; possibly several people on a task list
• Item size: a to-do list includes errands that take a few minutes; a task list centres on work with multiple steps
• Who uses it: a to-do list is personal; a task list is used by individuals and teams alike

How to Use a To-Do List: Five Steps

There are no fixed rules for writing a to-do list, but following this flow keeps it from ending the moment you write it.

1. Write down everything on your mind: ignore size and importance and put each thing on its own line. The goal at this stage is simply to get it all out of your head
2. Rewrite each line as a concrete action: instead of the slides thing, write list three fixes for the slides, starting with a verb. The point is that one glance tells you what to do
3. Pick what you will do today: do not try to do everything today. Mark only the items you will start on. Keeping the number small makes it easier to feel you got things done by the end of the day
4. Cross items off as soon as they are done: tick them or strike them through so finished work is visible. That sense of crossing things off helps you move on to the next item
5. Review at the end of the day: decide whether each remaining item moves to tomorrow or gets dropped. An item that has sat there for days is either vaguely worded or really a task rather than a to-do

Examples of wording

The same item can be easy or hard to start depending on how it is written.

• Vague: Blog, Expenses, Call back
• Concrete: Write five headline ideas for the blog, Enter this month's travel receipts into the expense system, Send the client three possible meeting dates

With vague wording, you have to work out again what an item means every time you look at the list. Making it a little more concrete when you write it means you can act the moment you see it.

Ways to Keep a To-Do List

Any tool will do. The best choice is whichever you are sure to see every day.

• Paper notebook or planner: you can start immediately, and striking items through is satisfying. If you forget to carry it, you cannot check it
• Sticky notes: one item per note makes reordering easy. They get messy as the number grows
• Phone notes app: always at hand, so you can write things down the moment they occur to you. Easily buried among other notes
• To-do app: lets you set recurring items and reminders. With many features, configuring it can become the goal in itself

Whichever you choose, keep your list in one place. Writing on both paper and an app means you lose track of where you wrote what, and one of them always falls out of date.

Advantages of a To-Do List

• Easy to start: no tools or preparation needed; you can begin today
• Prevents things slipping: because even small errands can be written down, minor oversights decrease
• Gives a sense of progress: crossing items off makes what you achieved in a day visible

Cautions

• Easy to write and never look at again: without a set time to review it, you forget the list even exists
• Quick items crowd out important ones: it is tempting to clear the fast items first, so important work that takes time keeps getting pushed back
• Too many items and you stop looking: as unfinished items pile up, opening the list becomes a burden. Regularly deleting things you will not do is necessary

When to Switch to a Task List

A to-do list is fine as a personal reminder, but consider managing work on a task list, with deadlines, owners and completion conditions, when situations like these arise.

• You have more work requested by others, or work you hand on to others
• Missing a deadline on some of your work would affect people around you
• Single items have started to involve several steps
• Your team needs to share who is doing what and how far along it is

You do not have to switch everything over. Keeping quick errands on a to-do list and work with deadlines or other people on a task list keeps both lists easy to read.

Summary

• A to-do list is a line-by-line list of things to do, kept so you do not forget
• A task list is a list of work to finish, with deadlines, owners and completion conditions
• To use one: write everything down, turn items into concrete actions, pick today's items, cross them off when done, and review at the end of the day
• Any tool works, but keep the list in one place
• When work with deadlines or other people grows, start using a task list alongside it
