1. Meditations — Marcus Aurelius
The personal diary of Marcus Aurelius (the last of the so-called “Five Good Emperors” of Rome), where he made notes to remind himself to follow the way of the Stoics, and admonishing himself when he didn’t. It’s an interesting collection of thoughts, and when removing the classical names, could have easily been written today.
I strongly suggest that everyone has a read of this book, as it’s a great into to one of the later Stoic practitioners, and give a practical view of Stoicism, but even if you don’t buy into the whole philosophy, there will be some points that’ll be of use to you.
Out of the hundreds of marked quotes, this one is my favourite:
“If you are distressed by anything external, the pain is not due to the thing itself, but to your estimate of it; and this you have the power to revoke at any moment.”
