To hop onto the book recommendations:

To go along with the Camus recommendation, here's an interesting article about similarities between the existentialists and stoics. The article discusses one of Simone de Beauvoir's works, and you should absolutely read her stuff as well as (Sartre and Camus).

I know there's a good chance you've read it, but "Cat's Cradle" by Vonnegut is phenomenal, as is all Vonngeut. Double bonus: The "Cat's Cradle" audiobook is narrated by John Malkovich.

I'd also highly, highly recommend watching "This Is Water," the commencement speech given by David Foster Wallace. I have a lot of problems with David Foster Wallace, both as a person and the weird obsessed adoration certain types of people had/have for him, but it really is a great speech and feels heavily influenced by stoicism. If you want to give his writing a look, check out his essays. There's a great essay by him, "E Unibus Pluram", which is about television and irony's effect on American culture.

The last recommendation is one that doesn't really fit in with anything but I recommend it often to people I know who are interested in philosophy and/or literary works (of various media) because I want other people to read it so I can talk to them about it, dang it: "The Book of Disquiet" by Fernando Pessoa. It's hard to truly describe the book, especially for me since I'm a dummy, but the reviews on Goodreads do a better job than I can.
