Why I Wrote the First-Time Supervisor Survival Guide — LLeanStore Journal

When I first entered manufacturing, I didn't start as a operator/staff.

I became a supervisor almost immediately. Not because I was naturally gifted at leading people. But because my Japanese language skills were needed to work closely with a Japanese advisor.

Looking back, I realize I stepped into leadership before I truly understood what leadership meant. At the time, I thought being a supervisor meant working hard, solving problems, and helping everyone around me. Then one day, my manager said something I still remember.

*"You are incapable as a leader."*

Hearing those words was painful. I felt shocked. I felt sad. But if I'm honest, a part of me already knew I was struggling.

I understood the technical side of the job. I could translate. I could organize work. I could solve process problems. But leading people was something completely different.

So I did what I usually do when I don't know something. I started learning. I searched for books about leadership and supervision, hoping someone had already written the answers I needed.

Most of the books I found were excellent. But they were written for business executives, CEOs, or entrepreneurs managing large organizations.

Very few spoke to someone like me—a new supervisor trying to survive the first few months of leadership on the shopfloor. I couldn't find the book I needed. So I learned the hard way.

At first, I led one or two people. Then three. Then ten. And before I fully understood what I was doing, I suddenly found myself responsible for around forty people.

The responsibility was overwhelming. Every day brought new questions.

How should I give feedback? How should I handle conflict? When should I step in? When should I let someone learn from experience? How could I support the team without trying to solve every problem myself?

Many of those lessons came through mistakes. Some came through difficult conversations. Some came through long days where I wondered whether I was really cut out to lead.

Years passed. I continued learning, reading, observing, and reflecting. Ironically, many of my biggest leadership insights arrived later—when I was no longer directly leading a team.

Distance gave me perspective. I could finally see the mistakes I'd made and the lessons they had taught me. That's when I realized something.

The book I had been looking for all those years didn't exist. So I decided to write it.

The *[First-Time Supervisor Survival Guide](https://lleanstore.gumroad.com/l/SupervisorGuides)* isn't a book written by someone who believes they have all the answers. It's written by someone who remembers exactly what it feels like to stand where you are now.

Confused.

Overwhelmed.

Trying to do your best while quietly wondering if you're good enough. In many ways, every chapter is a message to my younger self. A collection of lessons I wish someone had shared with me before I stepped into leadership. And if reading this book helps one new supervisor avoid even one mistake that I had to learn the hard way, then every page will have been worth writing.
