Enjoying your work or working to enjoy life?

A friend of mine said the other day that it is not realy necessary to find a job that you realy enjoy. The idea is to do something such that you have the resources to do the things that you enjoy. So if we were always were looking for a job that we would enjoy we would be forever starting afresh and then would be stuck at quite a low salary range for a while hence wont be able to do other things that we enjoy. Ok that was a bit confusing but well there is somewhat of a point there. Though i'm not so sure I agree with it. The big flaw I see in that argument is that most of us work 5 - 6 days a week till at least 6pm so unless we have brilliant time management skills how are we actually supposed to do all these things out of work? The maximum we'd get it one day per week and even if we do get to something we enjoy then i don't think its worth not enjoying you self the other 6/7th of the time. I mean I totally see it happening even with those around me - cannot go out on weeknights because you must come home and sleep to get up early the next day - even if you plan something for the evenings more often that not there maybe something to prepare for the next day and then thats gone - even on sundays whole day affairs cannot be planned casue that is the only day you have to tidy up your homes and do other domestic stuff.
