And for what? Doing more of the same I don't really like, so that my employers profit even more of my work? I can't convince myself to spend time that way and don't believe I could do it for more than a couple of weeks before burning out. So, maybe you start liking what you do if you become really good at it. But there is an assumption, that anyone can become really good at what they are doing. Or if I remember that book correctly, that case was covered by noticing that everyone else is going to drop out of the profession. In any case, not everyone drops out of the profession who isn't good at it and not everyone who stays inside the profession will become good eventually. But sure, whose who are really good will properly enjoy it.
It seems like maybe your goals in life don't line up with becoming "so good they can't ignore you?" I don't intend that as an insult in any way -- everyone has different priorities in life, and I don't know you, so it's also possible that you _are_ "so good they can't ignore you," and the book is incorrect.
Even outside of work, don't you find it satisfying to do something you're really good at? A dumb example: I love skiing, and the better I get at it, the more fun I have doing it. It's not because I enjoy showing up the people around me -- using my skills just becomes more enjoyable the better I get.
