The ToDo system I kept for 10+ years

06 Dec, 2025

I've been doing personal task management using a markdown editor for 10+ years.
Sometimes I tried ToDo app things but eventually I quit it because of my laziness.
Even ADHD-friendly apps, I couldn't adapt to it. (I'm diagnosed ADHD).

The method is basically do

• Create new file (like "diary.2025.12.md") in beginning of month
• Update lists everyday
• Use Google Calendar if need alarm

- 2025/12/1
  - [ ] 10:00 haircut
  - [ ] dispose bulky garbage
- 2025/12/2
  - [ ] 15:00 job interview
...

Additionally I write some sections for writing long-term plans or thoughts.

## review of last month
blablablabla...

## monthly plans
- [ ] go to ward office
- black friday sale
  - [ ] buy new nvme ssd?

That's it. You have no need to hopping many ToDo list apps.
You have countless options for markdown editors but I recommend using Obsidian.
And if you use Obsidian, there is some option to sync between smartphone and PC.

• Obsidian Sync (paid)
• "Self-hosted LiveSync" plugin (free, self-hosted)

I use Obsidian Sync instead of LiveSync for a specific reasons and I'd like to write in another time.
