Brainstorming - Throw it all down

We recently were brainstorming a new character at work. The lead was going down a path for a spell the character could do, there was an alternative that I could see but I didn't bother to mention it because it seemed totally obvious to me and the lead seemed so excited about his current idea. Then someone else mentioned the idea that I had and the lead loved it even more then his first idea, so I guess it wasn't as obvious as I originally thought.

Lesson: Throw down every idea, even if it seems dumb or obvious.
