(Seneca (1997). On the Shortness of Life. Penguin Books: London)
I’m a big fan of Stoic philosophy and this book by Seneca is a great starting point. Most people go straight for Meditations by Marcus Aurelius. But this book really does allow you to dip your foot in the water of Stoic philosophy without feeling you’re being indoctrinated into a way of viewing life. The book has many observations on life that make you sit back and appreciate. For example, one favourite entry of mine is how Seneca explains that life isn’t short at all, in fact, it could be too long if done correctly. There’s obviously much more to this passage, but thoughts such as this really make the reader sit back and think things through along with how they could make positive change and maximize their current and future possibilities.
