Johnson learned this from a powerful friend who would call, make a single blank statement, hear one back, say 'I love you, see you', and hang up, all in about fifteen seconds. Over a couple of months of these micro-calls they built a genuinely deep friendship. The mechanism swaps the currency of friendship from time (which busy people lack) to frequency and specificity. Williamson pairs it with two tactics: text friends the instant you think of them (often with an old photo), and 'assume familiarity', dropping the verbose 'Dear Brian, I hope you and the family are well' formality for a quick 'thinking of you, hope all's good'. Because the investment is tiny, a non-response costs nothing, which removes the fear that keeps people from reaching out at all.
Origin
A powerful friend introduced Johnson to 15-second phone calls that built a deep friendship over a couple of months; Williamson independently arrived at 'text your friends when you think of them' as a top life hack.
Core principles
- 01Busy people can't spend time, so friendship must use a different currency
- 02High-frequency micro-contact compounds into real depth
- 03Assume familiarity; skip verbose formality
- 04A low bar means a whiff costs you nothing
- 05Reach out the moment you think of someone
How to run it
- 1
Reach out the instant you think of them
When a friend crosses your mind, act immediately with a quick call, voice note or text rather than waiting for a 'proper' occasion.
Pro tip An old photo you find of the two of you is a high-impact, near-zero-effort opener.
- 2
Keep it to 15 seconds
Say the one thing, exchange a warm sign-off, and end. Brevity is a feature: the other person can pick up because they know it won't cost them twenty minutes.
- 3
Assume familiarity
Drop the over-formal preamble and speak as if you're already close: 'Hey man, thinking of you, hope all's good.' Formality signals distance; casualness signals closeness.
Pro tip You can overshoot into brisk or entitled, so keep warmth in it.
- 4
Keep the bar low
Because each touch is tiny, a non-response or a friend who isn't ready costs you nothing. Low stakes remove the fear that stops people reaching out.
Pro tip If you whiff, you've invested almost nothing, so there's no sting.
- 5
Repeat to compound
Sustain the high-frequency micro-contact over time; the small touches accumulate into a friendship as fluid as ones built over decades.
Pro tip Johnson and Williamson report going months without talking yet staying fully in sync via this pattern.
In the wild
Johnson's friend would ring, make one blank statement, hear one back, say 'All right man, I love you, see you' and hang up, roughly fifteen seconds. Repeated over a couple of months, these micro-calls built what Johnson describes as an amazing, deep friendship, without either person spending the hours their schedules didn't have.
→ A deep, high-trust friendship built entirely on tiny, frequent contact.
Common mistakes
Waiting for the big hang-out
Treating friendship as a four-hour event you have to book weeks ahead makes contact rare and lets relationships wither; frequency beats duration.
Over-formal messaging
Verbose, formal texts signal distance and raise the effort bar; assuming familiarity keeps the touch light and frequent.
Is it for you?
Best for
Anyone whose meaningful friendships stall because 'let's hang out' feels like a big, rare, high-friction event.
Not ideal for
Relationships that genuinely need deep, uninterrupted in-person time to repair or deepen.
