For people interested in Stoicism, I can recommend the book Meditations by Marcus Aurelius. There are a couple of very accessible English translations (the original text must be in Latin). The book is basically a collection of many thoughts that are roughly one sentence to a page long and self-contained. So you can read it any way you like, in any order. There are some really inspiring thoughts in the book, though some of them might be difficult to relate to since things have changed quite a bit in almost 2000 years.
I'm actually going through this book right now, and I like it a lot. Sometimes you need to dig a bit deeper and cross-confirm with examples from your life to get something meaningful out of it. I can't agree with everything the stoics thought, especially Marcus Aurelius was sometimes contradictory in his own beliefs, and also with the actual stoics - sometimes he leaned epicurean. In any case though, it's difficult to not agree with his very sound observations of humans and human nature that continues to be valid today.
I also picked this book up once before, the project gutenberg version, and I stopped reading after a chapter, because the language was kind of impenetrable and I found myself spending more time decoding what was being conveyed than actually thinking. Then I found the Hays translation (with the red raven on the cover), and I love it now. He prefers clean prose over conveying the original verbiage, which can be convoluted. Of course, there is a certain amount of interpretation in the hands of the translator that comes with that, but I don't think it's enough of a big deal in this case. If you really think this impacts the meaning, you can reread passages in another edition simultaneously. I recommend it, it's not as expensive, and it's a dollar if you get it used.
