Sometimes you can know the likelihood. It&#x27;s not a nihilistic hole that you throw things at and see what sticks. Stuff that people go out of their way to do, even though it isn&#x27;t supported is a good clue. Stuff that someone keeps ranting about in your meetings is another. Stuff that bugs the hell out of you personally is a third. Iteration is more important than inspiration, but you certainly don&#x27;t go into it blind?
