I've started using planners several times in my life. I've abandoned most of them too.
The first attempt was back at university.
I bought a large notebook, divided it into days, and wrote down what I wanted to do. Finished something? Cross it off. Didn't finish it? Move it to tomorrow.
It worked for a while.
I liked being able to open the notebook and see what I'd actually done that week. My days felt less blurry.
Then the system started becoming work of its own.
Every morning I was writing the same things again: exercise, English, training, everyday routines. Unfinished items kept moving forward. Miss a few days and suddenly the planner itself felt like another thing I'd failed to keep up with.
Eventually, I stopped using it.
Years later I tried paper again during a stressful period at work.
This time I was less interested in productivity. I wanted to make sure my life outside work didn't disappear.
I wrote down walks, rest, movies, English and calls with people close to me.
I also drew a calendar on the notebook cover and marked each day with something like 🙂, 😐 or 🙁.
At the end of the month, I could look at those marks and get a rough picture of how the month had actually felt.
I liked that.
A few months later, that notebook ended up on a shelf too.
When planning becomes another job
A planner can become surprisingly demanding.
Make the plan.
Rewrite unfinished tasks.
Copy recurring routines.
Keep everything organized.
Deal with the task you've already postponed for three days.
Then you have a normal Tuesday when you're tired and don't fill anything in. Now the planning system itself makes you feel behind.
That didn't work for me.
I didn't want to be disciplined about maintaining a productivity system.
I wanted something much smaller: decide how I wanted to spend the day in the morning, then spend a few seconds looking back at it in the evening.
Most of my days aren't that different
In 2024 I built a simple tool for myself.
The first version looked exactly like you'd expect from a backend developer building something quickly: default Bootstrap, blue buttons, very little design.
The main idea was reusable day templates.
I realized that most of my days follow a few familiar patterns. I have normal workdays, workdays with sport, and weekends. The details change, but a lot of the structure repeats.
So why recreate it every morning?
I make a template once, choose it for the day, then change whatever is different.
Maybe today's sport is boxing instead of swimming. Maybe I want to study English, work on a side project, or deal with something specific.
Planning takes very little time.
That was much easier for me to stick with than starting from a blank page every morning.
Ordinary things belong in the plan too
My daily plan can contain things like drinking a glass of water, doing morning exercise, calling my mom or going for a walk.
Those aren't impressive productivity tasks.
They matter to me anyway.
It's easy to spend an entire day being busy with work and reach the evening without having moved much, talked to people close to you, or done anything that felt like your own life.
I like seeing those things next to work.
The plan reminds me that a day also contains health, rest, relationships and things I enjoy.
Pick one focus
Later I added a Focus of the Day.
It's one thing I want to keep in mind that day.
Sometimes mine is English or sport. Sometimes it's rest. It can be calling someone close to me or even something like "don't complain about work today."
The focus doesn't need to be an ambitious goal.
For me it answers a simpler question:
What matters to me today?
That's different from treating every item in a long todo list as equally urgent.
A day can still be good when some boxes stay unchecked.
The evening check-in can take seconds
Another habit that stuck was rating the day from 1 to 5.
I usually do it in the evening.
I also mark whether I followed through on the day's focus.
There's a journal too, but writing is optional.
I used to write more. Lately I sometimes go for weeks without writing many long entries.
I still use the rest of the system.
That's one reason I think journaling habits can be hard to maintain. If the habit requires a thoughtful page of writing every evening, eventually there will be a night when you don't want to do it.
A rating takes a few seconds.
Sometimes that's enough.
Why rate a day at all?
One rating tells you almost nothing.
A few months of ratings are different.
In March 2026, I was working at a job that wasn't a good fit for me. My average daily rating for the month was 4.4.
In April, after that period ended, it went back up to 4.88.
Sometimes the data surprises me in the other direction.
A few difficult days can make the whole month feel bad in retrospect. Then I look back and see that most of the ratings I actually gave those days were fairly high.
Memory changes with your current mood.
A small record gives you something else to look at.
It won't explain why a day was good or bad, but it gives you a reference point.
Two years later
I've been using some version of this system for about two years.
I haven't used it perfectly.
I've taken breaks. Some days have no plan. Sometimes I barely write in the journal.
The last time I checked my 2026 stats, I had created a plan on 191 out of 229 days and rated 186 out of 229.
I like that the system survives imperfect use.
I don't want a 500-day streak that becomes stressful to lose.
Miss a day.
Come back tomorrow.
Over time, the history becomes useful on its own. I can look at ratings by month, read old entries or export a period and go through it later.
I've done that a few times.
Old entries from trips or difficult periods are especially interesting. You remember the broad outline of what happened, but the small details disappear surprisingly fast.
Reading your own words brings some of them back.
Try the system without an app
You don't need a special app to try this.
Tomorrow morning, open a note and write a short plan for the day.
Pick one thing you want to keep in mind.
At night, come back to the note, mark what you did, and rate the day from 1 to 5.
Write a few sentences if there's something you want to remember.
If there isn't, don't.
Try it for a week.
The goal isn't to complete every item. Pay attention to whether your days feel different when you give them a little structure in the morning and look back at them for a moment at night.
Stoic Diary
That small personal system eventually became Stoic Diary.
I built reusable day templates, a daily focus, ratings, an optional journal, history and statistics. My wife and I still use it ourselves.
You don't need to wait for Monday.
Just plan tomorrow.
