I don't think it is passion that makes a developer successful. I've always found it to be two things: give a shit and critical thinking. Too many devs are lazy and just want to be done, play whack-a-mole. Others take a "I'm just doing what I'm told" approach. I want to add value, even if I am not passionate about the value I am adding. When you take time to understand the problem and think out how best to solve it (including things like time and money) and then give a shit enough to solve it in the best way you can, you will always add value and when you are always adding value, you will be content, happy and feel pride in your accomplishments.
