I used to scribble on table with crayons holding in my little hand when i was a kid. A few years later, I've found that my canvas has switched from table to books. Yes, I loved to scribble along pages of my textbook so bad, especially during class.  When I got my first drawing pad in undergrad, I felt like I've found a new continent of my own. From that time on, I know my life is complete.
