Passion to Profession: Building a Career on Content and Taking the Leap with John Walaszek

Stacking Slabs

What does it look like to turn your passion into your profession more than once?


In this episode of Passion to Profession, Brett sits down with John Walaszek, Content Strategist at PSA, to unpack the path from music blogs to the sports card industry.


John didn’t wait for permission. He built.

He started a blog when no one replied to his emails.
He created content when no role existed for it.
He followed what held his attention and turned it into a career.


Now he’s doing it again. This time in cards.


This conversation covers:

  •  Why doing the work before the opportunity matters 
  •  How building on the internet became his resume 
  •  What he learned working inside major media and record labels 
  •  Why authenticity still wins, even in crowded markets 
  •  The gap between music content and sports card content 
  •  Why the hobby still feels early from a content standpoint 
  •  What it takes to make the jump into the industry 

If you’ve ever thought about building something around what you care about, this one will hit.

Because the path isn’t linear.
It’s built through action.
