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.
People are different form all other people in this world. While some go for painting and sketching, other do other. As for me, when i fell stressed and tired, i read books and listen to music, especially to the old songs and classics. The songs remind of my childhood days and relax my body and mind.
