I liked this book. I've read Marcus Aurelius' work in the past, but the other two authors are fairly new to me (I mean, I know who they are, but I never actively read their works - just passively read selections in various philosophy classes).
I often get asked about my opinion on political issues, and I often say I don't really care one way or the other. This seems to irritate a lot of people. I think I already have a measure of stoicism within me. Here is a quote: "Ask, 'is this something that is, or is not, in my control? And if it's not one of the things that you control, be ready with the reaction, 'Then it's none of my concern.'" (p. 2).
The first part of the book is "Enchiridion" by Epictetus. I found myself agreeing with him - and noted that a lot of what he says align with things I say and with how I often act. Chapter 33: 2 (Let silence be your goal for the most part; say only what is necessary, and be brief about it), Chapter 33:14 (In your conversation, don't dwell at excessive length on your own deeds or adventures), for example.
The second part of the book is Seneca's "On the Shortness of Life," in which he postulates that "It is not that we have a short time to live, but that we waste a lot of it." Seneca believed it is important to make room for leisure in life, but a life of pure leisure is considered meaningless. Seneca defines actual living as being in control of yourself, enjoying yourself meaningfully, and working towards goals that are important to you. This part I didn't care for as much - it was just too much about death and a little dry without a lot of insight for me.
I loved the third part, parts of Marcus Aurelius' "Meditations." So many good quotes. "Today I escaped from all bothering circumstances - or rather I threw them out. They were nothing external, but inside me, just my own judgements."
Although the middle was slow, I enjoyed this foray into stoicism.
