Contrary to popular belief, just because you do graphic design, it does not necessarily mean you have fantastic drawing skills. Graphic design is such a wide umbrella that encompasses advertising design to 3D modelling. One does not have to be skilled in the traditional tools of art such as pencils and paper to be a designer.
However, that is the way I fell in love with art in the first place. Traditional hand-drawn art on paper with pencils never ceases to amaze me.
