Not everybody works with something they like. Even less people works with something they love. A ridicolously low rate of people actually get to work with something that makes them laugh to the point of getting in the way of the job itself.
When working with imagery, we get to see stuff. To see things only our creative mind is able to create, or emulate. And THAT, is something we, as artists should be careful. Our work may actually be so fun that gets us distracted, or may be so weird that we get some rookie mistakes for not getting too much attention into it. It may be contrary to our beliefs, making us question the very reasoning behind working on it, or i may be so hot we get distracted, or even too nice to work on, making us over-focused and overconfident.
The thing is, paying too much attention to our work, makes us (artists) get away from reality, from what actually keeps us working and motivated. We should always focus on our work, but at the same time, keep in mind that our line of work only exists together with our relationship with reality, if we lose it, our work is directly affected.
Just yesterday, I was working on a specal portrait for an easter egg for the game. I won't tell you guys about it, because (obviously) it's an easter egg (ha! it's almost easter already). However, this easter egg illustration got me, and I felt like laughing every three minutes I spent drawing it.
It wasn't getting me far, and I looked for a way to concentrate more on my work. That way was music. Usually I don't put much attention to the kind of music I'm listening to when working, if I like it, I keep listening to it. But this time, I needed some power-focus-songs and for that purpose, I can only think about one or two of my favorite artists.
So, I got my headphones and rushed some hours finishing the work that'd take me some more time if I kept laughing every three minutes, thanks to the focusing power of progressive rock.
