Why did Pyotr Ilyich Tchaikovsky leave his job at the Ministry of Justice?

Pyotr Ilyich Tchaikovsky resigned from his position as a clerk at the Ministry of Justice because he made the definitive decision to dedicate his life to music.1

After completing his studies at the Imperial School of Jurisprudence, Tchaikovsky initially pursued a career in the civil service as his parents had intended. However, following his exposure to music classes at the Russian Musical Society and his subsequent enrollment as one of the first students at the St. Petersburg Conservatory, he chose to abandon his administrative role to focus entirely on his musical education and career.1
