It's still not about the idea.

You're assuming that the idea is going to make you give up years and friends for. It's the person that does those things. Personality traits are much more important here.

And if you've ever seen an idea through to successful conclusion, the end state always looks different (sometimes vastly) from the initial seed. So the idea wasn't important except to charm the person into going through the process.
