A book based on Big Long Now .com published by Atomic Activities.

From the back cover:

AA: Hi Rafaël, how have you been?
RR: Very good, so good, better and better.
AA: Better than before?
RR: Definitely. I actually thought I was happy before, but I fooled myself.
AA: Fooled yourself?
RR: I thought I was happy, I really believed it, so maybe I was. But I’m so much happier now so how could I have been happy at the time? It’s hard to trust my own memory, and it’s hard to measure my own feelings. But I’m very sure I’m happy now.
