Ambient Maintenance

After reconnecting, prevent the slide back to dormant. Set quarterly calendar reminders for top contacts — to deliver a small, specific signal of attention, not to 'catch up.' That beat is cheap insurance against the fade that quietly undoes most reconnections within a year.

Ambient touches — sharing an article, congratulating a promotion, reacting to a post — each cost under 60 seconds and keep the thread alive without another scheduled call. Reference something specific every time.
