Painting and sketching are the ways to express yourself. For some people it is their obsession, for others it is a way to relax their minds. While others consider it a way to make a connection with their inner-self. In any case sketching and painting are something intricate yet soothing and fascinating.
I believe that to display your art you do not have to be a great artist. You just have to draw you emotion and personality on paper.
For me it really helps to relax my mind when I am sketching,
It is my way to enjoy some of my free time I really love to sketch whenever I got a pen and notebook I would usually start to draw or doodle in my notebook.
