Just like we were all taught in English class to map out and brainstorm, you essentially have to do the same thing in design. Prior on starting your web, logo, icon, poster, business card, print, or any other type or design you have to get a general idea of which direction you will be headed. I’ve said this plenty of times before, and I will say it again. You cannot build a house without blueprints. If you want potential future stress go right ahead and be my guest.
