What was the reason that you joined MBBS?

So as we know, majority of the people that join MBBS say that they want to provide free service to the needy and poor, help the society, make lives better. But are those the only reasons why people would join MBBS? I'm genuinely curious to know if there would be any other reasons. I'm currently in Second Prof. Year (just started) and the reason that I choose MBBS was when I was reading Biology in classes 8-10 and I was the only one who was able to understand the mechanisms, physiology of organ systems and explained them to my friends before exams. From then on, I felt like I had a natural affinity to human body and it's physiology, and wanted to learn more about the body that is full of mysteries. So in short, I joined MBBS to learn more about Human body. Sure I want to help people, but all of them are secondary to me. (I hope I didn't offend anyone by saying this)
