Making checklists of things you're looking for in a person is the numero uno thing you can do to guarantee you'll be alone forever.
I don't have a checklist. Whatever material excites me, they'll call for a certain genre or combination of genres. It'll come naturally and I'll be eager to learn how that thing works. I learn the rules, and I'll probably break some of them.
You get a checklist, and then you just sort of ride herd on it. It's just a few items on a single sheet of paper.
I don't think we're ever going to be in a position where we can say this is the template, this is the checklist, that must be met [for intervention].
But something, somehow, had made all these paths converge. You couldn't find it on a checklist, or work it into the equation. It just happened.
The checklist is one of the most high powered productivity tool ever discovered.
