Every two months, I get an allergy shot. Xolair. Not a big deal — just part of my routine.
The clinic has one rule: call 30 minutes before you arrive. They need time to prepare the injection. If you don't call, you wait. Maybe 20 minutes, maybe more.
My real assistant used to handle this. She was good. But every once in a while, she'd forget. I'd show up, and they wouldn't be ready. No big deal — 20 minutes in the waiting room. Except I'd also be mentally kicking myself for not having a better system.
So I built one.
What the Agent Actually Does
My Lindy calendar agent checks my schedule every morning. When it finds an event with “allergy shot” in the title, it does the math: if the appointment is today, it sets a trigger for 30 minutes before.
At T-30, an AI phone agent dials the clinic.
But this is where it gets interesting: the clinic has an automated phone tree. Press 1 for the Westlake location. Press 2 for something else. The automated voice reads it out, then waits. A machine calling another machine.
I had to figure out the timing manually. After the call connects, wait exactly 23 seconds — that's how long the recorded greeting takes. Then send a “press 1” DTMF tone. Wait 15 more seconds for the menu to cycle. Then when a human picks up, deliver the message:
“Hey, this is Lindy calling on behalf of Thanh Pham. Thanh is on his way for a scheduled Xolair shot and will arrive in about 30 minutes. Just wanted to give you a heads up. Thank you. Have a great day.”
When the call finishes successfully, Lindy sends me a Telegram message confirming it went through.
I don't think about allergy shots anymore.
Why This Is the Best Automation I've Made
I've built things that automated 20+ hours of executive briefing prep. I've put together AI agents that research 26 people before a dinner event and generate a full dossier. I've set up workflows that handle hundreds of emails a week.
The allergy clinic thing is smaller than all of those.
But it might be the one I'm most satisfied with. And I think I know why.
The big automations are impressive. They save enormous amounts of time and change how entire workflows function. But they're also obvious targets. Anyone who's thought about AI for five minutes would say: “Of course you'd automate executive briefings.”
The allergy clinic automation is not obvious at all. It's a routine task that happens every two months. The kind of thing that falls through the cracks because it's infrequent enough that you never build a real system for it. And when you forget, it's not a catastrophe — just a minor inconvenience.
That's exactly why it's worth automating. Because those minor inconveniences compound. And because the mental overhead of remembering to do something is often worse than the task itself.
My real assistant forgetting the call wasn't the problem. The problem was that I was carrying around this background awareness: has anyone called? Should I double-check? That's the kind of low-grade mental weight that adds up across dozens of similar tasks.
When the agent handles it and sends me a confirmation, that mental weight goes away. I don't think about it. I show up and the shot is ready.
“Life Gets Better One Agent at a Time”
I say this in my AI workshops: life gets better one agent at a time.
Not one giant system. One agent. One task. One workflow.
The people who build the most effective AI setups aren't the ones who start with the biggest vision. They're the ones who start with something small, prove it works, and keep going. After six months of that, they have five or ten little automations running in the background — and collectively, those things make their life noticeably different.
The allergy clinic call was my entry point for AI phone agents. Now I use the same pattern for other calls. I understand how IVR navigation works. I know how to time the pauses. That knowledge came from building something small and slightly silly.
The Right Question to Ask
When people ask where to start with AI automation, they usually want an impressive example. Executive briefings. Department-wide email handling. Something that sounds worth mentioning at a networking event.
Those are fine. But the better question is: what's the recurring thing in your life that you occasionally drop the ball on?
Not the big stuff you track carefully. The medium-small stuff you do every month or two. The phone call you sometimes forget. The follow-up you mean to send but don't. The check-in with a client that happens sporadically enough that there's no system around it.
Those tasks are usually fast to automate. And the return — not just time, but mental quiet — is higher than you'd expect.
Start there.
