According to Keith (From Keith Richards: What I've Learned:, on the Esquire website): "There's this perennial thing that people have - how do you do it? Why do you do it? Like it's - what do you do? How do you go to an office every day? Compared to that, my job is easy."
And what's the hardest work of all? According to Keith (via What Would Keith Richards Do?): "That's the hardest work of all, bein' lazy. But you can't just make a profession out of laziness - you have to work really hard at it."
