In conversation with an ex-colleague yesterday, she dropped the following anecdotal gem while recounting a chat with a first year teacher up north:

"You can discontinue the search for the perfect worksheet, you know. There isn't any ideal lesson plan that will always work, there's no brilliant plenary task that solves all your classroom management woes.

There's just you and them, and whether they think you like them or not. Get that right, and the rest will follow."
