You're not dull. Creativity is a loaded word. To me creativity is a state of play.

Have you ever played as a child? Chance are you did. Are you able to do stuff you enjoy without anyone forcing you to? That's creativity.

My creativity is computer science related. For others it's painting, poetry, dancing or being a top fragger at Counter Strike. Just find out what is fun for you and maximize it. That's innate, and we don't lose it with age, we lose it because we become too busy to deal with bollocks imposed upon us.

And why should you maximise play? Because it's the point where drive, focus, fun and personal accomplishment are maximised. That's what I aim for.
