Principally, for me, it's not the principal of not enjoying the work. The issue is better aptly stated as: Is this what I want to be doing when I'm 70? I knew a guy in his 50's, worked at the same place for thirty years. Died at work (of a heart attack). There's so many other things in life than just work. ...but the beautiful thing about our profession is that we can keep coding, whether we're employed or not (FOSS). So, why would't you want to race to retirement, to be able to do the other things that you love (say, surfing every morning or painting or hiking or what-have-you) and still code? That's the best of both worlds, really.
