By day: A job which pays the bills and is reasonably secure. I have a house to pay for. My job does not define me as a person, except that it is the sort of job that might encourage a person to claim that their job does not define them as a person.
By night: Fritter away the hours in an off hand way. Sleep.
For fun: Drink. Socially, of course. And unsocially. I sometimes play the guitar, though less often than I used to, and less well.
