Work is a means to an end. If you don't enjoy it -- and I know you don't -- you can at least remind yourself it shelters and feeds you. People who love their jobs are lucky. That usually means they get on well with the other workers, often so much so that they carry on to the pub or coffee shop together at the end of the day.
If you get no satisfaction from your job -- and I know you don't -- it takes effort to put something else in place. People join out-of-hours interest groups or take up a sport.
I don't think you're going to generate more enthusiasm for your work by making it the centrepiece of your existence.
Life's very tough on those who choose to go it alone.
