I too have been doing this recently, especially thinking about my teaching career.
I can't remember what I did yesterday, but events of years ago are so clear in my mind. Thinking about pupils and could I have been kinder or had more patience with them when they were disruptive, has been niggling away in my head.
I envy my husband's capacity to compartmentalise things and move on. I wish I could turn the clock back, but hindsight is a great thing!
