I view "do what you love" / "find your bliss" from the other side. Given programmers A and B, of equal ability, where A loves programming and B is just in it for the paycheck, I expect A to be more successful. Not for magical karmic reasons, but because they'll put more in more study, more effort, and more hours toward the magic 10k.

Love isn't all though; it's possible to really enjoy coding but be a terrible programmer. Love won't fix that.
