I had a startup partner who was like this. It was exhausting. The reason a-pivot-a-week is not the same as a lean startup is because with such rapid pivots there is no way your changes are based on data. It's not pivoting; it's just churning. Steve comes close to saying this, but I think it'd help to take all these ideas and gush about them to someone outside the company. (He suggests an advisor; I'd say a spouse or a friend.) Once you get it out of the system and think about it for a few days, then talk about it with your co-founders/employees.
