Hi fun2lean,
that guilt sounds pretty familiar. Though I do not see it so negative. I love to burn for my pupils and I do not have the feeling to burn out as I get enought "fuel" back from them.
Anyway I know that things will be different, when I am going to have own children. When I plan my lessons, I consider how much of the planning I can reuse next year, so I can save time long term.
Great post, keep up the great work.
Thank you for your encouragement. Definitely we always run the extra mile for our students and students are our motivation to move further in this journey.
