Take one photo.
That's all.
Bisa (微差) is a record-keeping app that simply records one photo per day.
You can add a short message or not.
There's no sharing on social media. Don't show it to anyone.
Just keep one photo for yourself.
--
■ No praise. No encouragement. No advice.
Bisa looks at the photo and writes only two lines.
"Today" and "Center of Gravity."
Today: A heading describing what happened that day.
Center of Gravity: Where your eyes were directed.
It doesn't say anything more.
It doesn't encourage growth. It doesn't force reflection.
It doesn't even say, "That's a nice photo."
--
■ Patterns become visible in 7 days.
Once you've accumulated a week's worth of records, a summary arrives.
What you were looking at.
Where your eyes were directed.
Just that, quietly.
And then, one question arrives.
A question you don't need to answer.
But a question that lingers, just a little.
--
■ In 30 days, time becomes visible.
The days you thought were "the same every day"
When you open the calendar, they're all different.
As a month's worth of records accumulate,
Your own "pattern" begins to emerge.
What do you tend to focus on?
In what situations do you pause?
This isn't something someone teaches you;
It naturally emerges from your records.
