I think this author's point was more of a person that would find working on a business more interesting but instead is painting right now and hating every single day that they have to put brush to canvas. Some people find certain sets of activities more interesting than others. If I were a professional farmer, I would not enjoy it very much; but there are many people that would. Similarly, there are people that would find developing or testing software to be the most boring job they'd ever seen ... and yet I enjoy it.
