Teaching an Old Dog New Tricks

From a wooden door on two file cabinets to AI — the tools changed everything. The work ethic didn't.
Let me paint you a picture.
It's 1986. The office is a wooden door laid across two steel file cabinets — a desk improvised from whatever was available. On it sits a telephone, a desk blotter covered in handwritten notes, and a Rolodex fat with business cards. Stacked nearby are business encyclopedias, phone books, and geographic manufacturers' directories. On the wall, maps — actual paper maps — marking territories, target accounts, and the roads between them.
That was the tool stack. That was how business development got done.
No internet. No CRM. No email. No search engine. If you wanted to find the right contact at a manufacturing company in suburban Chicago, you opened a directory, found the company, wrote down the number, picked up the phone, and started talking.
It was slow. It was manual. And it worked — because the fundamentals underneath it were sound.
The Toolkit Evolves. The Fundamentals Don't.
Over the next four decades, the tools changed. First came personal computers, then email, then the internet. Directories gave way to Google. Phone books gave way to LinkedIn. The Rolodex gave way to CRM platforms.
Each new tool created a moment of choice: adapt or fall behind.
I chose to adapt. Every time.
Not because I'm naturally a technology person — I'm not. I'm a salesman. A grinder. Someone who believes in the power of a well-researched target list, a genuine outreach, and relentless follow-through. But I also believe that refusing to use better tools out of habit or pride is just stubbornness dressed up as loyalty to craft.
The craft is the fundamentals. The tools are how you practice the craft faster.
Then Came AI — and Everything Accelerated
In the last few years, something different happened. Not another incremental tool upgrade — a genuine leap.
Today the daily toolkit looks like this:
ChatGPT — for drafting, brainstorming, and synthesizing complex information quickly
Gemini — for research, data analysis, and pulling insights from large documents
Claude — for long-form writing, strategic thinking, and nuanced content development
Perplexity — for real-time research with sourced, current information
Grok — for fast takes on current events and market developments
Five AI platforms. Each with a different strength. Used together, they compress what used to take weeks into days — and what used to take days into hours.
The market study that took weeks of manual research through Hoovers, manufacturers' directories, and DoD websites 20 years ago? Today it takes only days. The outreach that required individually crafted letters and phone call sequences? Today it scales with personalization that still feels genuine.
The work is the same. The pace is completely different.

What Didn't Change
Here's the thing nobody tells you about AI: it doesn't work if you don't know what you're doing.
The tools amplify judgment. They don't replace it. If you don't know how to identify the right market, AI won't tell you. If you don't know what a qualified prospect looks like, AI won't qualify them for you. If you don't know how to build a relationship, AI won't build it.
What AI does is take everything you know — built over decades of doing the actual work — and multiply its reach. The research moves faster. The outreach scales. The synthesis that used to live only in your head gets organized and communicated more clearly.
But the fundamentals underneath? Those haven't moved an inch.
Know your ICP — who exactly are you trying to reach and why
Research before you reach out — understand the business before you contact it
Be specific — generic outreach gets ignored in every era
Follow through relentlessly — the grind is still the grind
Build real relationships — AI can't shake a hand or remember a spouse's name
Those principles worked in 1986. They worked in 2007 when I was mining DoD websites and mailing letters to rebuild two distressed studios. They worked in 2016 when I built a $2.5 billion target list from annual reports and paid subscriptions. They work today.
The Blessing Is Open-Mindedness
Getting comfortable is the enemy. Not age — comfort.
I've watched talented people get left behind not because they couldn't learn the new tools but because they decided the old way was good enough. It was. Until it wasn't.
The salespeople who couldn't adapt to email in the 1990s fell behind. The ones who couldn't adapt to LinkedIn in the 2000s fell behind. The ones who can't adapt to AI in the 2020s are falling behind right now — and most of them don't know it yet.
Open-mindedness isn't a personality trait. It's a competitive decision. Every new tool is an opportunity to widen the gap between yourself and everyone who decided they were too old, too experienced, or too set in their ways to learn it.
This old dog is always up for new tricks. Not because it's trendy. Because it works.
Still Working Half Days
Forty-plus years in, and the alarm still goes off early. The work still gets done. The clients still get results.
The desk has changed. The tools have changed. The pace has changed dramatically.
The work ethic? That was never going to change.
Some of us work half days. 6 to 6. And we love every minute of it.
