This post from What's Best Next was a real eye-opener. Here's the part that stung:
Some people fancy themselves as being “creative,” or ”creative-types,” because they have a lot of ideas. Cool. You have ideas. So does my 3 year old. That doesn’t make you creative. An idea without implementation isn’t creation. It’s imagination.
There you go. I've been well aware of my shortcomings for a long while, you know, the book I haven't written, the painting I haven't done, the cartoons I haven't drawn. Of course all the while I would've said I was a creative person.
But what does 'creative' mean, after all? Generally, being creative means something gets created.
