Ask HN: Are you doing what you want to do or what you have to?

I have recently started watching the new National Geographic show 'Genius' about Albert Einstein. The way Einstein was obsessed with Physics took me to my childhood days when I used to ponder over why everything is the way it is. I always wanted to become a physicist. But being an Indian, I was repeatedly bombarded with the idea how essential it is to make a living. As such, I strayed from what I wanted to do and got into engineering (CS). It's now the end of my engineering and I am now occupied with the thoughts of what my life had been if I would have chosen the road not taken. It's not that I don't have a good job, but the thought of losing a chance to do something I love that keeps me awake these days. Personally, I think that the advancement in technology is also responsible for this. The internet, though providing us the means to access a vast amount of information, has also taken from us our ability to question things. Rather than thinking of the solutions on our own with our imagination, we now resort to Googling stuff and finding the answers straightaway.
