A practical system that survives a busy week. No willpower required.

Key takeaways
In Contact Book, every contact has a stay-in-touch cadence field. Never. Weekly. Biweekly. Monthly. Quarterly. Yearly. The point isn't to be precise - it's to put each person into a rough lane that the system can nudge from.
A useful starting heuristic: how would I feel if we hadn't spoken in three months? If the answer is "sad / surprised / something must have happened", they belong in monthly or shorter. If it's "oh nice to hear from you", they belong in quarterly or yearly.
After every meaningful interaction (a phone call, a dinner, a long voice note), open the contact and log it. One sentence is enough. "Talked about Sara's job change, said yes to brunch in May." That's the whole entry.
If you wait until tomorrow morning, the texture is gone. The next session you'll just see your calendar entry and write "talked". The whole point is to capture what you talked about so the next conversation has a thread.
Life events are the non-routine moments - birthdays, anniversaries, weddings, kids being born, parents in hospital, big work changes, moves between cities. These are the moments where reaching out matters most and where the system carries the weight you can't.
When you hear a life event coming, log it the same day. The reminder fires a few days before, and you write the message you would have sent if you'd remembered.
Every Sunday evening, open the dashboard, look at the overdue lane (people whose cadence has lapsed), and pick three. Send a message to each. That's it. Five minutes. The point isn't depth - it's continuity.
