On Creativity, by Andy Rutledge at A List Apart.

How’s this for a definition of creativity?

Creativity has nothing at all to do with self-expression or flamboyancy. Aside from the simple ability to create things, the most important feature of creativity is a highly developed perception filter that is somewhat less common than we’re led to believe. Despite what we were taught in school, we don’t all possess significant creativity, and fewer of us still have any skill at employing it. True, anyone can make something, and anyone can make something up. In this mundane sense, everyone is creative. But this basic truth belies the design-relevant definition of creativity, and ignores the fact that each one of us has different creative abilities.

Effective problem solving is, I think, the same as working creatively, and as a web, or graphic designer, or a developer or coder, devising solutions for clients and their problems (or design requirements), is indeed being creative.
