Introduction
A huge thank you to Valerija Kirjackaja for her continued support as guest coach. This week I had an idea that I didn’t have time to test and implement, due to other life priorities, so I feel very grateful to be able to lean on the people around me for support.
This feels like a real Valerija classic, so if you’ve been around for a few years you may have already picked up a few of her tricks!
