As someone who does this because it's a decent paying job, I don't think this comment is fair. I think I'm quite skilled, and I've been told so consistently. I don't have passion; I have discipline and professionalism. I take my job seriously. It pays well, and I make sure that I deserve that paycheck.
Passion for me is a nasty world, in the mouth of bosses. It's almost always a way to ask people to work unhealthy hours, and it results in bad work being done, which I have to fix later. If people talk live their own passion, it's fine, but whenever I hear someone appeal to the passion of someone else, it's to sell them into doing something that's not in their best interest.
