The Mentor I Never Had — And the One Thing I Tell Every Junior Marketer Now

Nobody sat me down in my first year and told me how any of this actually worked.

I learned marketing the way most people in my generation did — by getting thrown into a campaign, watching it half-succeed, half-fail, and piecing together the "why" on my own time, usually late at night, usually after everyone else had gone home. There was no senior person checking in to ask if I understood what had actually driven the result, or if I'd just gotten lucky. I assumed that was normal. It took me almost a decade to realize how much time it cost me.

I'm not writing this to complain about a mentor I didn't have. I'm writing it because I now run into the same gap constantly, sitting on the other side of the table, and I think most companies are still solving it wrong.

If you'd asked twenty-five-year-old me for career advice on how to find a mentor, I wouldn't have known where to start. Nobody around me talked about it as something you actively went looking for — a business mentor or a career mentor felt like a lucky accident that happened to other people, not something you could ask for directly.

The gap isn't skill. It's context.

Every junior marketer or growth hire I've worked with in the last several years has been sharper on tools than I was at their stage. They know the platforms faster, they pick up new AI tools without blinking, and honestly some of them build dashboards I'd have needed a week to figure out.

What they don't have — and what almost nobody hands them — is context. Why did we choose this channel over that one. Why did the client push back last quarter and what did we actually change because of it. Why does a campaign that looks identical to last year's suddenly perform half as well. That kind of knowledge doesn't live in a course or a certification. It lives in the heads of people who've sat through the failures and stuck around long enough to see the pattern repeat.

I didn't get handed that context early on. I built it the slow way, through trial, error, and a fair amount of quiet frustration. And for a long time I assumed that was just the cost of entry — that everyone has to earn it the hard way, so why would I make it easier for the next person.

Why I changed my mind

A junior team member once asked me a question in a meeting that, five years earlier, I would have found embarrassing to ask out loud. Something basic about why we were segmenting an audience a certain way. Half the room went quiet, the kind of quiet that signals "everyone thinks this is obvious." I answered it properly instead of brushing past it, and it turned into one of the more useful ten minutes of that project. Her next campaign was noticeably sharper.

That's when it clicked for me. The cost of not explaining context isn't just a slower learning curve for one person. It's a team that keeps relearning the same lessons individually instead of building on what the last person figured out. I'd been treating hard-won knowledge like something people had to earn through suffering, when really it was something I could just... give away, and get a stronger team back in return.

What mentoring actually looks like now

I don't run formal mentorship programs, and I'm skeptical of most of the structured ones I've seen — they tend to produce a lot of scheduled coffee chats and very little transferred judgment. What I do instead is smaller and more constant, and it's the same approach I'd recommend to any junior marketer looking for a mentor rather than waiting for a program to assign them one.

When I make a call on strategy, I try to say the reasoning out loud, not just the decision. When a campaign underperforms, I walk the team through what I think went wrong before anyone gets defensive about it, so it becomes a shared post-mortem instead of a blame exercise. And when someone asks a question that feels "too basic," I've made it a rule to never let the room's silence answer it for me.

None of this is generous, exactly. It's self-interested. A team that understands the why behind decisions makes fewer of the mistakes I already made for them. That's not charity. That's just better team design.

The one thing I tell every junior marketer

If there's a single piece of career advice I repeat more than any other, it's this: don't wait for someone to explain the reasoning. Ask for it directly, even when it feels like you're supposed to already know. And if you're a junior marketer wondering how to find a mentor, stop waiting for a title or a formal program — the best career mentors I know never had "mentor" in their job description. They were just people willing to answer the question everyone else was too polite to ask.

I wasted years assuming the senior people around me had a system I simply hadn't been shown yet. Most of the time, they didn't have a system either — they had scar tissue from past mistakes and an instinct they'd never bothered to put into words. The people who asked me to explain my thinking, even when it made them look less experienced in the moment, are the ones I've watched grow the fastest.

I still think about that mentor I never had. Not with resentment — just as a reminder of what I owe the people sitting where I used to sit.
