Trying to be original is a diversion from the real job, which is making the instrument make the sound that fits what you are trying to play. Originality sneaks in when you're not looking, and probably when you are trying to do something else, filling a gap in the music.

It's no different from when you're talking. You're trying to communicate, get something over in a way that convinces or explain or carry a picture. Saying things in a different way is fine, when it's a way of doing these things. Just for it's own sake, it's so much hot air.
