How did the humanists in Florence differ from Petrarch?

The humanists in Florence, such as Leonardo Bruni and Poggio Bracciolini, focused on promoting secular education and reviving classical literature, while Petrarch was more known for his emphasis on poetry and the revival of classical languages. Petrarch also had a more personal and introspective approach to his works, with a focus on individualism and the concept of Humanism.
