The 52:52:52 project, launching both on this site and on social media in early 2024 will help you address 52 issues with 52 responses over 52 weeks.

A Mundane Comedy is Dominic Kelleher's new book, which will be published in mid 2024. The introduction is available here and further extracts will appear on this site and on social media in the coming months.

This site addresses what's changing, in our own lives, in our organisations, and in wider society. You'll learn about key changes across more than 150 areas, ranging from ageing and time, through nature and animals, to kindness and love...and very much else inbetween.

Halcyon's aim is to help you reflect on how you can better deal with related change in your own life.
