How to follow through on the promises you make to people
Most broken promises are small ones made in passing. Here’s a seven-step habit for catching them, keeping them and letting people know you did.
Quick answer
Most broken promises aren’t broken on purpose. They’re small things said in passing, like “I’ll send you that article” or “let’s grab coffee next month,” that never got written down. To follow through, catch every promise the moment you make it, write down who it’s for and what “done” looks like, give it a date, and look at your open promises once a day. Keep the list short by saying yes less casually, and when you can’t deliver, say so early.
Why small promises matter so much
People rarely remember the exact words of a conversation, but they remember whether you did what you said. Sending the intro you offered, checking in after the interview you heard about, or returning the book you borrowed are small acts that quietly tell someone they can count on you. The opposite is true too. A string of forgotten “I’ll get back to you”s makes people stop taking your offers seriously, even if each one was minor.
Step 1: Notice when you’re making a promise
Casual promises hide in everyday phrases: “I’ll send it over,” “let me introduce you,” “I’ll check and let you know,” “we should catch up soon.” The first habit is simply hearing yourself say them. If it would be a little disappointing for the other person if you didn’t follow through, treat it as a real commitment.
Step 2: Capture it within a minute
Memory is the weak link. Write the promise down right away, before the next conversation pushes it out of your head. A quick note on your phone while you walk to the car is enough. Waiting until the end of the day is how promises get lost.
Step 3: Make it specific
“Help Jordan with the job search” is a wish. “Send Jordan the intro to my friend at the design studio” is a task. For each promise, note three things:
- Who it’s for.
- What done looks like, in one line.
- When you’ll do it, even if it’s a rough date.
Step 4: Keep promises next to the person
A promise is easier to keep when it lives with everything else you know about that person. When you next think of them, or see them, the open commitment is right there instead of buried in a general to-do list between “buy milk” and “renew passport.”
Step 5: Review your open promises daily
Spend two minutes each morning looking at what you’ve promised and to whom. Do the ones that take under five minutes right away. Sending the link, making the intro, or replying with the answer you said you’d find is usually faster than keeping it on your mind.
Step 6: Close the loop out loud
When you finish, tell them. “Just sent that intro to Sam” or “Found the name of that restaurant: it’s Lucía’s” lets the other person know you remembered, which is half the value of keeping the promise.
Step 7: Promise less, and renegotiate early
The easiest promise to keep is the one you didn’t make casually. Before you offer, ask yourself if you’ll realistically do it this week. If something changes, say so before the deadline rather than after: “I haven’t forgotten the intro. I’ll get it to you by Friday.” That keeps trust intact even when you’re late.
Promise phrases to watch for
| What you said | What to write down |
|---|---|
| “I’ll send you that.” | Send [the thing] to [name] by [day]. |
| “You should meet my friend.” | Introduce [name] to [friend], with one line on why. |
| “Let me know how it goes.” | Check in with [name] after [the event] on [date]. |
| “Let’s get coffee soon.” | Message [name] with two dates that work. |

Frequently asked questions
Why do I forget the promises I make?
Most promises are made in passing, in the middle of a conversation, and never written down. Without a note and a date, they compete with everything else in your head and usually lose.
How do I keep track of what I promised people?
Write each promise down within a minute of making it, with who it’s for, what done looks like and a rough date. Keep it next to your notes about that person and review open promises daily.
What should I do if I can’t keep a promise?
Tell the person before the deadline, not after. A quick message saying you haven’t forgotten and giving a new date keeps their trust far better than silence.
How can I stop overcommitting?
Before you offer something, ask whether you’ll realistically do it this week. It’s fine to say “I’ll think about who might help” instead of promising a specific intro.
