Regarding general student (or teacher) wellbeing, ever share anything like John Wooden's Pyramid of Success? 
I have shared this with my National Honor Society club and have had students try to focus on one task per week to revisit at our next meeting. I have found myself looking to adhere to some of these items as well which has helped as the year gets going. I have also used Shaka Smart's more abbreviated version with my varsity basketball team. Anyone else use these?
