Teachers are born planners

I don't know why this is so hard to understand. You have to be able to plan, in order to teach. I don't mean that you have to be able to write down your plans or even that you always have to stick to them. You just always have to have a plan. Maybe 2, in case one fails. I can think of no other profession where you need to know what you are going to do, practically minute by minute. Lawyers and such have to bill minute by minute, but that can be done after the actual work. It is not however, possible to decide at the end of a long school day what exactly it was you set out to accomplish, and how. Plans change, and you have to be able to change them all the time as a teacher. You also have to live with your plans when you CAN'T change them, and that makes teaching unique.
I think what policymakers miss about education and teaching is that there is a subculture within every school that makes every school different. But there is also a culture of schools that makes teaching in any school highly similar. They are places where people are segmented and classified, whether they are in charge or not. A place where everyone is simultaneously a leader and a follower, at all times. And a place where bathrooms are always ill-placed. Where one person ( or 2, on rare occasion) have the absolute power, except when they don't. Where politics and agendas play an equal role to childish antics.
