Listening to Start the Week on Monday, I heard Grayson Perry give a brilliant definition of sanity:

“Sanity is being all of yourself, to everyone, all of the time.  Not schizophrenic or chameleon-like.”

Authenticity follows on from this: “Authenticity means bringing all of yourself to bear on a topic” – in other words, bringing your whole self to the work.

So, if it feels like your job might be driving you insane, you could be right.
