Mid week with a slow start

I am away on course for two days. At certain parts of the day, I do miss going back to school. I feel that I am more effective teaching in my class rather than to sit there all day long to try to absorb whatever the lecturers tossed at us.
And it gets harder to zone out when they insisted that we have group discussions.
This week is a relatively a slow week. I am running low on energy and I do not have the mental strength to plan ahead. Perhaps tomorrow is a more productive day for me.
