One of the activities is named : I call it "positive journal"

The aim of this activity is to be able to appreciate and grateful for ourselves, I personally always forget to say " thank you" to myself. This activity will help students to reflect what have they done positively towards themselves. The key reason is if we know how to appreciate ourselves, it will be very easy to appreciate others as well. We won't be hesitant to say one good word and it can create a safe space between students and teacher. 

I would use this activity after a long week with pressure or a hard time. But this activity can be used as a morning routine in classroom. It will expand their positivity towards others. 

Instruction:

It needs paper or notebook and pen, giving them some prompts to get ideas what to write "Three things you are grateful for this week" and so on.

This activity gives students some time to reflect and helps them to improve mentally.
