Our brains evolved to treat outreach as danger and to forget people, so go easy on yourself, then build systems that compensate.
The idea
Your 12000th-great-grandfather never sprinted off from the berry patch because he was late for coffee with a prospect. His wiring was built to survive the next 24 hours inside a small tribe, where stepping outside it was dangerous, and ours hasn't changed much. E.O. Wilson put it best: "We have Paleolithic emotions, medieval institutions and godlike technology." We can keep up with only about 150 relationships (Dunbar's number). Memories fade once we stop paying attention. We'll take a small reward now over a far bigger one later. None of that makes you a bad professional. It makes you human.
How to do it
Recognize that your default hardware isn't built for what you're asking of it.
Be a little easier on yourself.
Then implement solutions: a time block, a database instead of your memory, a cue that prompts you.
Start with 30 minutes once or twice a week: open your CRM, update a handful of contacts, reach out to a few people.
Example
Say you're resisting contacting a past client, even though you did great work and ended on a high note. Don't feel bad. For your caveperson uncle, doing something socially "unsafe" really was a risk. All your peers have the same resistance, and most of them will let it win. You can be one of the few.
Watch out for
Absolution is step two of three. Understanding the wiring only pays off once you build the system.
The Spiral of Loneliness: Loneliness triggers stress and hypervigilance that make us less likely to reach out. Knowing it's wiring is the way out.
The Five Barriers to Maintaining Relationships: We can only track so many people, relationships decay, networks shrink with age, modern life multiplies the noise, and we're wired for the short term.
The Recurring Calendar Appointment: Pick a regular time based on your energy and calendar gaps, make it a recurring appointment, and defend it.
Falling Off the Wagon: When you lapse, give yourself grace, drop the backlog, and restart right away with one tiny action, like a single email.
