Do you like to make art? Do you like to write? Would you like to design clothes or buildings? Then you are a creative person.
Creative has to do with new things coming into being: creative is the opposite of destructive. Art class and art schools are good places to be creative. All the artists in a place are known as the "creative community." But being creative isn't just about art — to make anything new or come up with any kind of an idea takes creativity and is therefore creative. Whenever you're making something worthwhile, you're being creative.
