Q&A: Improve coaching skills

My dream is that you’ll one day have a mindset, strategy and execution coaching certification, selfishly so I can take it, but I also feel the industry needs more coaches like you! I’ve heard you say you don’t want to create a certification, though. So, I wanted to ask if you have recommendations on resources for how to learn about and improve the skill of coaching? Are there books, tools, or practices you recommended? Thanks so much for all the value you provide!
