An awesome story, good for you!
I’m a chemist and also thought that my passion is my major. But something happened inside me. It is hard to explain. Like I’ve just woken up and realize that it was a bad dream with wrong dreams:) Two weeks ago I started to learn programming. I really like it and hope after some time I will write a good story about my experience.
I added your story to bookmarks and will reread on occasion for inspiration:)
