Sketching is not just a form of art. It is a way of life, visualisation of your dreams and your character. Sketching is the quickest way of representation, a form of meditation and a rare skill that not everyone is dedicated towards learning because many people are scared that it's too difficult or you need to have a talent. I wasn't born as an artist, I had to learn it as well. I always wanted to draw like one of my childhood friend as she could do it effortlessly and I could not. Do not let this stop you from entering this magical world. It is truly life changing and both an enjoyable and profitable hobby or job (in my case!) to have.
