BEING A TEACHER IS A DIFFICULT TASK NOWADAYS, SO I DECIDED TO FOLLOW THIS PIECE OF ADVICE BY BRUCE LEE:
Empty your mind, be formless. Shapeless, like water. If you put water into a cup, it becomes the cup. You put water into a bottle and it becomes the bottle. You put it in a teapot it becomes the teapot. Now, water can flow or it can crash. Be water, my friend.
