You love to draw. It's magic to take a blank piece of paper and with some scribbles here and there it is now something that practically lives. It can cause an emotional effect, or an intelectual one. A few minutes ago it was a bare slice of wood pulp, now it's a mythical creature, or your grandmother, or your mythical grandmother.
How great is it when you draw something good and realize how much better it is than the ones you were doing last month? You can't not grow as an artist the more you practice. It's the way our brains work.
