This week, Iâm attending an arts conference and creative think-tank. A lot of the attendees are calling themselves âcreatives.â Now if you donât work in marketing or advertising, you may not have realized that creative can be a noun. So, what is a creative? A creative is an artist. Not just a painter or musician or writer. She is someone who sees the world a little differently than others. A creative is an individual. He is unique, someone who doesnât quite fit into any box. Some think of creatives as iconoclasts; others see them as rebels. Both are quite apt.
