If you haven't gone too far into the stoicism rabbit hole yet, I really recommend "Life of the Stoics", by Ryan Holiday. It's a compilation of the history (and probably myths from their time) of all of the biggest minds of stoicism.

Shows that they weren't always perfect, some of them were assholes, but others (notably Marcus Aurelius and Catho) lived the live they preached, and fought many battles (including literal ones) in ways that were different from their time.
