“People look at me like I’m an insane person. Do you know what I think is crazy?
Waking up at 6am, eating breakfast, getting in a car and sitting in traffic for an hour on your way to work, sitting in a box for eight hours, sitting in traffic on your way home, eating dinner in front of the TV and then going to sleep. Then repeating that process for the next 60 years of your life until you retire and then die.
I think that’s completely and utterly insane.”
