Haha, Let me tell you the story of mine. Maybe nowadays technologies, scope and many more factors going to lead you to make a decision to opt for a field or another.
But in my case, I took computer science as a subject because of the paint application (haha). The very first class and my first interaction with Computers in class 8th. I still remember Window 98 era. I was fascinated with the Paint Application. I was excited to know more of it, how this application is created, so I took Computer Science as a subject in Class 11th. But couldn’t get a well-derived answer and I wanted to understand this all. And so I did “The Engineering”.
