In 9th grade, I trained under a solid breakdancing coach. He was serious. Old school. You showed up, you put in the reps, you didn’t ask too many questions.

I respected him. But I got impatient.

He wasn’t giving me enough practice time. So I started training on the side with another teacher: his ex-student turned competitor.

He found out.

Fallout.

Not too long after, I quit breakdancing completely.

At the time, I blamed him. “He’s being controlling. It’s just dancing.” I was 15 and couldn’t see past my own bruised ego.

But, 12 years later, I understand something I didn’t at that time.

He wasn’t protecting his turf. He understood something I didn’t: two coaches meant two systems, two sets of corrections pointing in different directions, and a kid who’d never fully commit to either. He was protecting my progress.

Mastery comes from depth in one direction. Volume spread thin across two competing systems doesn’t build it: it delays it.

I see the same thing every week.

A founder gets a few months into LinkedIn. Posts are landing. A few good replies coming in. Profile’s gaining some traction. Then they wonder:

“Should I add a Substack? Maybe X? I don’t want to miss Bluesky.”

And I want to say: you’re switching to a second teacher.

So I tell them the same thing every time:

Tie expansion to your goal, not your boredom.

If you started on LinkedIn for lead gen, forget the timeline question. The only thing that matters: are you consistently getting monthly inbound from it?

No? Then you haven’t taken full advantage of LinkedIn yet.

More reps on the first platform. That’s the answer. The second one can wait.

The content angles, the audience trust, the DMs that turn into calls: none of that has compounded yet. Adding a second platform before it does doesn’t double your results. It halves both.

Your second teacher isn’t going anywhere.

Substack will still be there in 6 months. So will X. So will Bluesky.

But the window to build momentum on a platform closes faster than most people think. And splitting your focus before you’ve consistently hit your own goal is the fastest way to make sure you never do.

My breakdancing teacher tried to tell me that.

I just wasn’t listening yet.
