Design is about so much more than just sticking some information on a page. Design is about balance (not necessarily symmetry.) It's about knowing what feelings a font conveys and picking the correct font or combination of fonts for your message. It's about not overdoing it. Design forces you to take into account things that you don't normally think about when you're looking at a printed page. I cringe now when I see a paragraph where the designer just clicked "justify" instead of manually adjusting the kerning of each line. I have become addicted to grids and guidelines. I have learned to minimalize and let the information speak above my design. I will never look at billboards and magazines the same way again.
