I agree that another way to look at it is "don't hate what you do" although I feel like a post about that would be aimed at a different group of people.
When I wrote this it was more directed at people who feel a little bit lost, and are wondering why they haven't found that one "thing" that they're passionate about. It's about telling them that they don't have to search so hard for it because it's probably right in front of them right now.
I think people that hate what they do are in a slightly different (though similar boat). Sometimes hating what you do can actually crystallize exactly what it is you love (because you can't do it as much anymore) and so I feel like the problem that those people face is more making the leap to spend time doing what you love even if it means taking more risk.
Thanks for sharing - I really agree with your point.
