People customize their physical working space and tools as a way to help maintain a sense of ownership to the work they do. It helps with morale. It's fine if you think of work as a soul-sucking activity, but not everyone feels they have to hate their work or that it's not a part of their identity. Even for those who do dislike/hate their work, these small things can help them cope with the toil.
