The quality of your ideas range from bad to good.
If you have a good idea, pursue it.
Anything less than a good idea needs to be left alone and closed, for now.
If you have an idea that is anything less than good, write it down, underneath it write why you believe it isn’t a good idea right now, and leave it alone.
The discipline to leave poor ideas alone will lead to more ideas filling that space, and more chance for a good, or even that one great idea, to be born.
