At the time, the book helped me develop a new way to see and receive the world. I then applied that into my own life to shape what type of ideas and projects I'd go on to pursue. It helped me find a type of clarity in where I'd focus my energy in the areas I believed in. And looking back, along with other things, I'm able to source the book as an important stepping stone to how I approach my work today.
