Oh come on people. That's just not true. My current job isn't enjoyable at all. I love my hobby of sausage making, and if I could do that full time I'd love it. Sitting around cranking out sausages, making recipes, experimenting with new stuff all the while making money doing it....that just sounds awesome. To me at least. I'm actually in search of ways to get into business myself and may be finding one this year.
Some people search there whole lives to "enjoy" the work they do 40+ hours a week. I think it should be something we aim for. Of course, if you don't have a passion for it then things might get annoying.
