I look at purpose as the guiding star. The compass. The soul. Steve Jobs once said “Design is the fundamental soul of a man-made creation”. And everything we do is design in one form or the other. And if you have a fuzzy idea of your own soul, your design will suffer. On the other hand, like Steve Jobs does, if you have a sharp idea of your soul and what footprints you want to leave, all your design will complement and reinforce that soul of yours.
