I am now working as a mentor to a junior programmer in my job after working in my current role for almost 1 year. And I constantly have to tell him what to do and how to code the right way. 

There was a time when I was being told what to do and what not to do. But now it's the other way around. 

Time flies and the world really does turn around I guess. I was the learner at first, now I make other people learn. We'll see where this current role takes me though.
