To me, it’s “in search of the lost time” by marcel Proust. In this hustle and bustle world where people build startups for high evaluation, money and reputation, reading this book is an oasis in the desert experience to me. It inspires me to rethink of my simple day, to pay more attention to details, to figure out why little thing become what it is, to cherish small achievements and to appreciate people. And more importantly it inspires me to be alone and use the mind to think about the world and rebuild it.
