i will

A poor teacher describes.
A good teacher explains.
An excellent teacher demonstrates.
A great teacher inspires.

when I will (and i say i will because definitely i will) be a teacher, 
you have no place in my class if you:
do not know how to dream
do not know how to imagine
you have no passion
you are not ready to be ridiculed with your silly dreams/ambitions
you only aim for perfection because failure is the name of my game — you’ll fail and fail in my class so that real world will be chicken to you
