I always believe that ''Experience cannot be explained. Experience can only be experienced".
Rafi sir was the one who took this to the level I cannot even comprehend. He exactly knows what he's doing at every hour, at every minute, at every second and every nano second. He's one such gem that everyone loves. You would have already learnt the concept, but you hardly realise you've been taught. You would have already experienced a lot in the workshop, but you hardly realise that you've put in any effort in achieving it. He makes learning so effortless.
Sometimes he had already identified the problems within you and fixed them, but it takes a conscious self-observation to bring it to your own self. He's a true Magician.
Finally, Experience can't be explained. Experience can only be experienced. If you want to experience that experience, here's a man who comes from that place :) !
