Mythologies by Roland BarthesRounding out the list: Seneca, Schopenhauer, Nietzsche.
I wouldn’t have become the writer I am if I hadn’t, in my early 20s, discovered the work of Roland Barthes.

The Architecture of Happiness starts from the idea that where we are heavily influences who we can be - and argues that it is architecture’s task to stand as an eloquent reminder of our full potential.
