Your desisn is not perfect. .
What design are you talking about?

The context of the thread; the designs that "game designers should not have emotions for their ideas" designs. All of them.
Be prepared to let any of them (or all of them) go.
Yes, be passionate about them. But don't hold them so closely that you refuse to advance. Game designers should have strong emotions for their ideas. If they didn't, I'd question if they were passionate enough to make great games. You just should be prepared to let them go, or as was stated above, kill them if necessary.
