Balancing Accountability and Empathy – On his podcast by Jonathan Cutrell, says that accountability is “the gap between what we said we would do and what we did”, not simply a punitive technique for dealing with coworkers who find themselves in that gap.

Pro tip: Science shows that reading literary fiction improves your empathy.

What Do You Do? Why Your Identity Should Be More Than Your Day Job – Kat Boogaard reminds us that it’s easy to typecast ourselves into a single life type, and wrap our entire entity around it.

Take joy in being a complex person who likes more than software development!

This one’s from a few months back but absolutely worth sharing. Compassionate Coding: Software Development for Humans by April Wensel. It’s her keynote from Voxxed Athens 2019. April promotes the concept of compassionate coding, and how to use empathy to build products for everyone.
