When you are having fun and creating something you love, it shows in the product. So when a woman is sifting through a rack of clothes, somehow that piece of clothing that you had so much fun designing speaks to her; she responds to it and buys it. I believe you can actually transfer that energy to material things as you're creating them.
I am a spiritual person in an eastern religion kind of way. I learned that happiness for all of us is a switch that you flick in your brain. It doesn't have anything to do with getting a new house, a new car, a new girlfriend, or a new pair of shoes. Our culture is very much about that; we are never happy with what we have today.
