Life is not perfect all the time.
Most of the time I write just about the good things because that's what I want to remember, that's what I want to be my focus, that's what gives me hope that tomorrow is going to be good too. But sometimes students don't listen well or they staple their paper on the right every single time or they ask questions they already know the answer too. And sometimes we lose people we love or we wake up late and feel rushed all day or we have so much to do it feels like it'll never get finished. Sometimes life is not perfect. And that's ok.
