Mistakes I Made Early — So You Don’t Have To

Lessons You Only Learn by Doing the Job

If Part 1 was about learning the trade the hard way, this part is about paying for those lessons.

No one starts out perfect in process serving or private investigations. Anyone who tells you otherwise is lying or hasn’t been doing this very long. Early on, I made mistakes—some small, some costly—but every one of them shaped how I work today.

Mistake #1: Knocking Too Soon

Early in my career, I thought effort meant action—drive up, knock, get it done. What I learned quickly is that patience beats urgency. Knocking on the door too soon tips your hand. Once a subject knows you’re there, the game changes. Observation should come first. Always.

Mistake #2: Talking Too Much

I learned the hard way that silence is a tool. In the beginning, I explained too much—who I was, why I was there, what the papers were about. That only created resistance. You don’t need to overshare. Be professional, be calm, and say only what’s necessary.

Mistake #3: Trusting “Good Information” Without Verification

Addresses were wrong. Work schedules were outdated. “He’s always home at night” turned out to be false. Early on, I trusted information because it sounded confident. Experience taught me to verify everything. Assumptions cost time, money, and credibility.

Mistake #4: Underestimating Documentation

I used to think I’d remember details later. You won’t. Dates blur. Times get fuzzy. Early mistakes in documentation taught me that your notes protect you. Courts don’t care what you meant to write—only what you actually did write.

Mistake #5: Not Trusting My Instincts Soon Enough

There were moments early on when something felt off and I ignored it—only to realize later my instincts were right. Experience sharpens intuition, but you still have to listen to it. If a situation feels wrong, it usually is.

Mistake #6: Taking Things Personally

This job puts you in the crosshairs of anger, fear, and blame. Early on, I took reactions personally. That’s a mistake. This work isn’t about you. Once I separated emotion from execution, everything improved—my safety, my accuracy, and my professionalism.

The Biggest Lesson of All

Every mistake reinforced one truth: this is a profession, not a side hustle. Process serving and investigations demand discipline, ethics, and accountability. Shortcuts don’t last. Reputations do.

Those early mistakes made me better. They’re the reason I approach every case today with preparation, restraint, and respect for the process. Thirty-one years later, the fundamentals still matter—and they always will.he body content of your post goes here.

What 31+ Years in Process Serving and Investigations Really Teaches You Learning the Trade the Hard Way When I first stepped into the world of process serving and private investigations more than 31 years ago, there was no YouTube, no Facebook groups, no online directories, and no step-by-step guides. You learned by doing—or you didn’t last. I didn’t start out knowing everything. Nobody does. What I had was determination, curiosity, and a willingness to learn the trade the right way—by getting out there, making mistakes, paying attention, and adapting. Back then, process serving wasn’t about apps, GPS tracking, or instant skip traces. It was about observation, timing, patience, and knowing people. You learned quickly that knocking on a door was often the last step, not the first. You learned how neighborhoods worked, how people moved, when lights came on, when cars left, and when someone was likely trying not to be found. I learned early that this job isn’t just about handing someone papers. It’s about professionalism under pressure. You’re walking into tense situations. Emotions are high. People are scared, angry, embarrassed, or outright hostile. How you carry yourself matters. Your tone matters. Your judgment matters. There were no shortcuts. If you messed up, the court didn’t care why—you owned it. That responsibility shaped how I approached every serve and every investigation. Accuracy wasn’t optional. Documentation wasn’t optional. Integrity wasn’t optional. As I expanded into private investigation work, the lessons only deepened. Surveillance taught patience. Interviews taught listening more than talking. Skip tracing taught persistence. Every assignment reinforced the same truth: this field rewards those who take it seriously and exposes those who don’t. Over the decades, technology has changed, laws have evolved, and expectations have grown—but the fundamentals haven’t. You still need to know how to read situations. You still need to stay calm. You still need to be ethical. And you still need to remember that every case represents real people and real consequences. Looking back, I’m grateful I started when I did. Learning the trade the hard way forced me to develop instincts you can’t download and skills you can’t fake. It’s why I’ve lasted over three decades in an industry that chews people up quickly. Today, when I work cases or support newer servers and investigators, I bring every one of those early lessons with me. This isn’t just a job—it’s a profession. And if you treat it that way, it will carry you a long time. Thirty-one years later, I’m still learning. But I’ll never forget how it started—one door, one decision, and one lesson at a time.
