Good advice to your future self is small and comes with a reason. “Charge your phone outside the bedroom, because the bad nights start with one more scroll” is advice you can use on a real evening. “Be happy” is not. Write five lines like the first one and you have a letter.
Why advice works better as a letter
You already have advice for yourself. It is the thing you told a friend last month and did not take, or the lesson you relearn every winter. Most of it never gets written down, so it fades by the end of the week. A letter gives it a place to stay and a date to come back.
A letter also changes the tone. When you talk to someone you care about, you do not lecture them for an hour. You pick the one or two things that matter and say them plainly.
Before you write, answer three questions on scrap paper. What have I learned the hard way? What do I keep forgetting? What did I tell someone else this year that I have not done myself? One honest line for each is plenty to start, and the third question is usually where the best advice is hiding.
Advice written now carries what you know this season. A letter keeps that knowledge from fading into a vague memory of “I think I used to do that.”
Speak to yourself by name, not as “I”
Try a short experiment first. Think of a choice you are facing this week, and describe it using “I”: “I need to decide about the new shift.” Then describe the same choice using your own first name, or the word “you”: “[your name], you need to decide about the new shift.” Read both lines once more and notice which one feels calmer.
Psychologists call this self-distancing. In 2014, Kross and colleagues reported seven studies in the Journal of Personality and Social Psychology. When people talked to themselves with their own name or with “you”, rather than “I”, they created more distance from their feelings. In short lab tasks, that wording went with less distress, and outside raters judged performance more favorably.
Those were short lab studies, not studies of letters written to the future. Read the result as a small hint, not a rule. It may still help you find a steadier voice for the advice part of your letter, and it will not work the same way for everyone. If your own name sounds strange in a sentence, give it a few lines before you decide. Plain “you” works too.
Four kinds of advice worth writing down
You do not need all four groups. Pick the ones that fit the reason you are writing today.
- What to protect: the habits, people and hours that keep you steady.
- What to let go of: the worries and duties that cost more than they give back.
- What to do on a bad day: one or two small actions you already know help.
- What you already know: the lessons you keep proving right.
Under each heading, write three or four short lines. Each line holds one sentence of advice and one reason. For example: “Protect the first hour of the morning for the task you keep postponing, because your energy is highest then.” That is enough. You do not need to explain the whole week.
Keep the lines short. If a line runs on for three sentences, cut it down to the part that you would want to read on a tired Tuesday.
Here is how the groups can look in practice. Someone who works long shifts might protect the drive home with the radio off, let go of answering messages after nine, take a ten-minute walk on a bad day, and remember that a hot shower usually helps. Four lines like that are plenty.
Advice to leave out
Not every thought belongs in the letter. Some advice makes the reader feel worse, and some promises the future cannot keep. Leave out three kinds of line:
- Guilt, such as “You should have done this by now.”
- Certainty about the future, such as “You will definitely be happier.”
- Vague orders, such as “Stop being lazy.”
Write the line the way you would say it to a friend. Instead of “You should have answered that email by now,” try “Replying to the hard email the same day is a fair place to start.” Replace “should” with “could”, and “you must” with “you might”. Then read the line again out loud. If it makes you wince, rewrite it until it sounds like something you would say kindly to someone you love.
A sample letter in the second person
Here is a short example you can adapt. It has five pieces of advice, each with one reason. Change every line until it sounds like you.
Dear [your name],
This is advice from the version of you who just got through a crowded spring.
Protect Sunday mornings. They were the only hours this year when nobody needed anything from you, and you were kinder by Monday.
Pay small bills the week they arrive. In April three of them piled up and ate a whole evening.
When you are tired, call your sister before you open the news. She knows the real version of you.
Say no early. The late no in June made two weeks awkward for everyone.
You will forget at least one of these. Pick it up again without a lecture.
[your name]
Each line names something you could point to, a Sunday, a bill, a phone call, and each reason comes from something that happened this year. That is what makes advice yours rather than a poster. Your letter can be longer or shorter. Keep the reasons.
Check it, then choose a date
Read the draft once before you save it. Each line should have a reason. No line should carry guilt or certainty about the future. At least one line should be something you can start this month.
For everyday advice, six months or a year ahead usually suits best: long enough for your habits to drift, close enough that the advice still fits your life. You can choose any date from tomorrow up to 20 years ahead, and we email the letter to you on that day, between 8:00 and noon in your time zone. Nothing is emailed when you write it, so keep a copy for yourself.
Write it now
Pick one of the four kinds of advice and write three lines, each with its reason. Read them out loud and soften any line that sounds like an order. Then choose a date six months or a year from now, and send the advice you would give a friend about to face the same year.
