Roadmap for Becoming a Strategy Expert

For all the experienced strategy professionals out there: If you were to re-learn strategy from the beginning with the end goal of becoming a strategy expert, what would your roadmap look like? Feel free to recommend books/courses for each phase of the roadmap.

I’d also really appreciate it if you could include which strategy background you’re speaking from (i.e. business, organizational, product, etc)

My background: I’m a young professional who’s been working in consulting for the last 3 years in the Data and AI space.

Thank you in advance!
