I can picture in my mind the image of a mechanic that likes and enjoys fixing things. But I do wonder how much of it is real joy. At the end of the day what drives most people is that they want to satisfytheir human needs. bring food to the table. That's life for most people on Earth, then can find meaning elsewhere. And even those who are "passionate", as I said, I do wonder how much of it is pure fun. I asked doctors and engineers about this before, many of them don't feel the constant passion that I see in the picture I imagined. Again, it's a small percentage of the time. When you see a happy patient, when things go as expected, when the final test passes... But what drives most people isn't passion. It's responsiblities and satisfying human needs. And can probably become a great software engineer without falling in love with programming. I'm probably over-analysing what you said though, I do get what you say.
