About this episode
Brett McGrath interviews John Walaszek about transforming passions into professions, focusing on content creation in the sports card industry.
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.
