I didn't know how long I was supposed to hold out, so I set it to the whole evening and folded in three days. When I started over, I set it to 10 minutes, and it was so laughably small that it actually worked. Here's how many minutes make sense, and how to extend, in one table.
Ten minutes is the baseline. It fits even a tired day, and after a failure it's a size you can easily return to the next morning. Extend by 10 minutes when a week has two failures or fewer. Hold steady at three or more. At that pace you're at 40 minutes in a month and past an hour in two. Starting at 30 minutes or more only suits people who already have phone-free evenings, and if you're up against a strong habit like short-form before bed, starting at 5 minutes is completely fine.
Ten minutes satisfies two conditions at once. First, it has to fit any day. Tired days, sick days, buried-in-work days: 10 minutes still fits. Second, it has to be easy to come back to after a failure. Fail at two hours and tomorrow's two hours feels heavy. Fail at 10 minutes and tomorrow's 10 minutes costs nothing.
Asking whether 10 minutes is enough points the question the wrong way. The value of 10 minutes isn't in the 10 minutes. It's in what they stack into. Week one's 10 minutes isn't about reducing phone time at all. It's about installing one motion in your body: putting the phone down at the same time every day.
| Week | Time | Goal | Rule for extending |
|---|---|---|---|
| Week 1 | 10 min | Learn the motion: same time, every day | Two failures or fewer, extend next week |
| Week 2 | 20 min | Get through the first boredom | Same |
| Week 3 | 30 min | Feel time coming back | Same |
| Week 4 | 40 min | Build one solid evening piece | Same |
| Week 6 | 60 min | The hour before bed | No need to extend past here |
| Week 8 on | 60 to 120 min | As much as you want | Fix it to fit your life |
To pick your number, look at last week: how much time did you actually spend without the phone? Half of that is a good starting size. None at all, start at 10. About 30 minutes, start at 15. An hour, start at 30.
The rule for extending is your failure count. Two or fewer in a week, extend. Three or more, hold. Five or more, shrink. Deciding the rule in advance drains the impatience and the self-blame out of it. Decide by mood instead, and you'll over-extend on good days and quit on bad ones.
There are shrink signals beyond the count, too. If you spend the whole time watching the clock, if you sprint to the phone the second it ends, if you start dreading the hour: the size is still too big. None of that means weak willpower. It means the body isn't used to that size yet. Shrink it.
There are extend signals as well. If the timer ends and you sit a few minutes longer without reaching for the phone, if the set time starts feeling short, extend then. I went from 5 minutes to 30 in a month, and I never once pushed myself to extend. I just extended on the days it felt short.
Extending is not the goal. Stopping at an hour is fine. A daily hour that holds beats an occasional three.
A dive in Sumbi starts with a time you choose, anywhere from 10 minutes to 4 hours. The way a haenyeo stays only as long as one breath allows, a first dive can be short. Finish and you open one shell, and longer dives raise the chance of meeting a deeper sea's creature a little. The pace of extending is yours to set.
Try your first 10-minute dive →When matters more than how long. It has to be the same time every day to settle into the body. Mine is 9 p.m. It's when my kid falls asleep and my short-form used to begin, so that's the hour the phone goes into the drawer.
Decide where the phone goes: the drawer, a bag, another room. In sight, 10 minutes is hard. Out of sight, even 30 comes easily.
Grab the phone the second the timer ends and the 10 minutes becomes a waiting room. Decide to leave it a few minutes longer, and 10 minutes quietly becomes 15.
One line from a phone-down day. When I'd grown from 5 minutes to 30 in a month, there was a day 30 felt short. That was the first time I wanted to extend without telling myself to.
