Happiness Habits

This may or may not be related to math ....

Discovered an old note listing three habits for happiness. I don't recall the source, some lecture recorded on youtube, I think.

1. 3 gratitudes: write down three things for which you are grateful
2. Positive memory journal: write about one positive experience from the last 24 hours that you would like to remember
3. Thank you: at the start of the day, write a thank  you note to someone in your social support network. Yes, this means you have to interact with them enough to have something to thank them for!
