Larson’s work thrived in college. He was given a four-year scholarship to Adelphi University for acting. He could command a stage, especially with comedic roles. Even when given a smaller role, he was said to “make a mountain of it”.

He was a frequent writer of the student cabarets, raunchy shows that had a Saturday Night Live essence. He wrote pieces on taboo topics such as sex, feminism, and family structures. These cabarets also taught him how to work fast. Oftentimes, the cabarets were produced over 2 weeks. He was constantly doing rewrites until he reached the product he was satisfied with.

​

Leaving college, Larson experienced a different side of being a creative: mass rejection. As opposed to college, where he was working on countless opportunities, the wider world brought fewer eyes to his work. He also stayed, creating work that was “too rough” for the world of commercial theatre. In his collegiate works, he leaned toward Brechtian tendencies, not knowing that these wouldn’t pass in the commercial world.

​

This isn't to say Larson didn't receive any opportunites. He wrote for children shows such as Sesame Street and Away We Go. He also produced many pieces for his friends who were also in the creative field. Whether it be a selection of sea shanties for a friend in film, or a piano composition for his girlfriend's dance recitals, Larson was willing to contribute.
