HI — Human Interaction — is a daily vitamin. You already know this instinctively. We’ve all heard the studies: babies who aren’t held, touched, or cuddled don’t develop normally. But what about adults? What about you?

When I got my first apartment in my 30s, I expected independence to feel like freedom. Instead, the silence hit me like a wall. I had achieved the goal… and accidentally isolated myself. Looking back, I wonder if that chapter set the stage for a string of failed relationships. We humans need proximity — even animals do. Pet a cat and listen to it purr. Are we really any different?

I’ve spent years in different coaching and learning communities, and something always stands out: people form bonds fast. They throw around the word “love” the same way most people say “hello.” Why? Because these groups meet a fundamental need. Connection. Belonging. HI.

Loneliness is now considered one of the major modern diseases. If you come from a big family, you may not relate — you might be wishing those relatives would give you five minutes of peace. That’s the paradox: too much or too little, and we feel it. The need doesn’t go away; it just shows up differently.

But here’s the point. You already know the cure.
If you’re lucky enough to have people around you — friends, family, coworkers, even pets — you already have access to HI. The need is so strong that people stay in bad relationships just to avoid losing it.

This idea branches into a thousand directions. Living alone vs living in a tribe. Why we need touch. Why communities form so quickly. How the brain fires off memories and associations nonstop. Each one is its own post.

But let’s stay with the simple truth:

You need Human Interaction.
You need HI.

Get some every day — even multiple times a day. Get it from people who make you feel good, who acknowledge you, who make you feel seen, heard, understood. Join a group where you feel welcome. Learn something. Engage. Don’t pretend you’re above it.

HI is not optional.
It’s as essential as sunlight, air, and the vitamins your body can’t live without.
