This was a wonderful read. Could someone who's gone down this path provide a reading list for someone interested in learning more?
- Marcus Aurelius' Meditations (make sure to get the Hays translation! By far the best). Aurelius was an emperor of Rome; Meditations are his musings to himself in later life. It's interesting to reading the internal grapplings of a man who was, to his countrymen, basically a walking god.
- Lucius Annaeus Seneca's Letters from a Stoic
- Epictetus' Enchiridion, which translates roughly as "handbook" and was assembled from the teachings of Epictetus, an exiled former slave, to those who traveled to live and study with him.
I strongly recommend all three. If you're interested in more modern interpretations of the above, a couple good jumping off points would be A Guide to the Good Life by William Irvine (which was mostly pretty good) or The Inner Citadel by Pierre Hadot (which studies Meditations). Ryan Holiday also has a book called The Obstacle Is The Way, though I didn't enjoy it as much as any listed above, to be honest.
A personal favorite gem which, found several years ago: http://stoicletters.blogspot.com/. This blog bundles Seneca's letters into a modern style of prose and is much more accessible while conveying much of the same meaning as the original letters.
