live to work or work to live?

As a young IT professional, I’m strugging with this issue. Judging by a lot of the posters here and with conversations with people outside of this forum, there aren’t too many people who actually like their job. It’s rare to find someone who loves their job AND is well paid.

What is your philosphy? Do you work to live or live to work? How many hours do you work a week? How much time do you spend outside of work studying and/or doing side jobs?
