Valid point, but still: I there are things you love, do more of them. Incorporate them into every day. Do not create a mystical double life that is divided into work and pleasure. Try to make room for one in the other.
Mmm. Your job doesn't have to be what you love. Those jobs don't tend to pay very well, and may stress you out by making you compromise your creative vision (or just leave you sick and tired of the thing you once loved). But it should at least be a job that you're okay with and doesn't leave you miserable.
