Steve Carell, who played the lovably inept boss Michael Scott on The Office, decided to leave the show at the end of the seventh season for a few reasons. The primary reason was that after seven years on the show, Carell wanted to focus more on his film career. He had already achieved considerable success as a movie actor while doing the show (e.g., "The 40-Year-Old Virgin", "Little Miss Sunshine"), and it's typical for actors to move on from long-running TV roles to avoid typecasting. In addition, there were some reports suggesting that Carell was not directly offered a new contract by NBC, creating a scenario where his departure was partially not his own decision. In an interview, however, Carell clarified that it was his decision to leave and not the other way around. Finally, Carell has mentioned his desire to spend more time with his family. Maintaining a balance between work and personal life is often a factor that actors consider, especially with the demands of a television shooting schedule. From a show perspective, Steve Carell leaving The Office allowed the writers and creators to explore new storylines and character development with the remaining cast. Keep in mind, although Carell’s departure was a significant change, The Office continued for two more seasons, diversifying its humor and focusing on other beloved characters.
