In my school we had a CS lab and we were supposed to do lab assignments.

I had a book which gave a basic introduction on event driven programming, and introduced me to two new functions which I couldn't have ever known(I got internet in 2013) if I had gone with just the curriculum, kbhit() and gotoxy(). With this new knowledge I created my first 2d game. And that feeling of creating something no one expects and something fun, which also gets you attention of the whole room(Nothing like that was ever created in that lab, it was a shitty school), made me realize that this is what I want to do for the rest of my life. 😃
