Not convinced yet? Here are a few more reasons to say ‘thanks.’

A 2018 study from the University of Chicago shows that we often overestimate the awkwardness a recipient of a thank you note will feel. Additionally, we tend to worry that our writing will be scrutinized, when in fact the reader rarely pays attention to that aspect of the note.

An article in Forbes gives seven benefits of gratitude, including better sleep, improved physical and mental health, less aggression and more empathy, and the potential for more meaningful relationships.

This Harvard Health Publishing article talks about how cultivating gratitude in your life can make you happier, and gives a list of ways to do it (including writing thank you notes!)

Both Brené Brown’s TED Talk on the Power of Vulnerability and, if you have a subscription, her Netflix special Call to Courage are great videos to watch if you want to learn more about how being vulnerable can open up your life to new possibilities and enriched relationships. Because sometimes it can feel a little vulnerable to say ‘thank you.’
