Why did Sir William Blackstone shift his focus from legal practice to teaching law?

Sir William Blackstone’s shift from legal practice to teaching was primarily driven by his lack of success as a barrister and his growing interest in common law.1

In July 1753, Blackstone decided to retire from his legal practice to concentrate on academic law and legal work in and around Oxford. That same year, he began delivering the first university lectures on English law, which were noted for their lucidity and charm. His academic career eventually led to his appointment as the first Vinerian professor of common law in 1758, providing the foundation for his influential Commentaries on the Laws of England.12
