On the Shortness of Life by Seneca

Interviewing Ryan Holiday at Rakuten Optimism meant brushing up on my Stoics along with his more modern, but I daresay no more or less practical, books on growth hacking, marketing and media. (I actually read this in the lovely Penguin Great Ideas paper edition. Tell no one.)

I read it on the back of an inflatable swan, and later in a rubber dingy, beginning in the water, but as it was the Bay of Fundy in Nova Scotia, before I got even half-way through, I was stranded.
