No matter what you are sketching, designing, brainstorming, writing… I'm a firm believer in starting with pencil. Using pencil in the first stages of design can be the difference of an OK idea to something amazing!
Ideas flow more freely when not constricted to the limits of a computer. The computer can be used to MAKE anything you might think up, but can't THINK for you. Nothing compares to the open minded creativity that flows from the tip of a good old fashioned pencil on paper. Next time you design something, get away from the computer and start with pencil!
