There are enough ideas, images, symbols, and experiences in your head already to work with for a lifetime. It’s a little like having a car with an unpredictable battery, though. Sometimes you get in and it starts right up. Other times, especially if it has been sitting idle for awhile, you turn the key and nothing happens.
Regular maps have few surprises: their contour lines reveal where the Andes are, and are reasonably clear. More precious, though, are the unpublished maps we make ourselves, of our city, our place, our daily world, our life; those maps of our private world we use every day; here I was happy, in that place I left my coat behind after a party, that is where I met my love; I cried there once, I was heartsore; but felt better round the corner once I saw the hills of Fife across the Forth, things of that sort, our personal memories, that make the private tapestry of our lives.
A lot of people in our industry haven’t had very diverse experiences. So they don’t have enough dots to connect, and they end up with very linear solutions without a broad perspective on the problem. The broader one’s understanding of the human experience, the better design we will have.
