What is it to teach, and what is it to learn when you're in IT? Richard chats with Don Jones about his on-going work on his book Be The Master and how it has evolved since its first publication in 2018. Don talks about how readers connected with him around the book and discussed their own efforts in mastery and teaching - which encouraged Don to revise the book! Remembering how we learn helps inform how to teach, and teaching strengthens knowledge, so everyone benefits - and there's a lot to know!
