How much do you know? Are you humble and say, "A little." Are you egotistical and say, "A lot." Or are you a realist who says, "Not enough." How much do you think you need to know to be a good designer? I think the answer is, "More than I can ever hope to." Every day you will learn more that will influence your Design. You will learn things that expand it or reinforce it. Let this happen. Allowing experience and inexperience influence what you do creates Design that is human and a vital. Experience is everything you know that you need to brush up on. Inexperience is everything that you don't know that you need to look up. The amalgamation of these opposites is the heart of design.
