i read this as a break from writing a functional spec. And i've already read Thinking Fast and Slow. And I know that I'm going to be wrong. And I know that no matter what i say to the client, they will say 'OK' and then wonder why i missed the estimate. And i also know that this is what normal looks like and when i'm in the middle of it and it seems as though it's a spaghetti diagram of dependencies, it will work itself out so long as i keep chipping away at it. this is a strange profession - i wouldn't build a bridge like this...
