You're probably not passionate about programming, you're probably passionate about crafting or completing something that involves some degree of simple puzzle solving or design. Or maybe you're interested in rule/logic based systems. That's the spark.

Programming was one of my interests too, but if someone offered to put £2M in to my bank account under condition I never wrote a single line of code again, well... I'd take it in a heartbeat and I'm pretty sure I could find another "passion" in the 20 years of my own life that that would buy me. Hell, if i didn't have to work, I bet I could find a half dozen passions.
