Draw what you see... Feel what you are drawing

During my study, one of my lecturers used to say, "draw what you see, not see what you draw..."
Well, that was the basic principal of (contour) drawing...

See, all of us can draw... there are no good or bad drawing...
It's just people's perspective on your artwork... and the purpose of it... a hobby... your job... way of expressing yourself... or assignment...? Whatever the reason is... believe in it..

I just wanna add a lil' bit on my lecturer's saying... "Just draw what you see, feel what you are drawing... and you can never go wrong... but if you're unable to feel it... well... keep on tryin'..."
