Teaching - Why Do It? Not all teaching is miracle conversions and epiphanies. Much of it is persistence - you turn up regularly. You stay with the processes that you know work even if the results aren’t immediate. You take suggestion and criticism. You don’t shirk the hard conversations with disengaged kids. You hold fast to the simple maxim that it is your classroom. You protect that space and what goes on there because it is only if you do that then kids can feel safe and secure and learn.
