Whether you are interested in football or not, the book on Pep Guardolia's tenure at FC Barcelona (The Barcelona Way) is absolutely fascinating from the perspective of establishing & maintaining high performing team cultures - a thoroughly recommended read!
When it comes to generating new ideas and ways of thinking, it was interesting to read that Guardolia doesn't solely rely on the world of football for inspiration. Rather, he follows current affairs, seeks out other experts, and draws on historical learnings by applying his footballing brain to internalise their relevance to football management. "In other words, he finds a lesson applicable to football everywhere" (p124).

I couldn't help but think about how an expert in any profession can easily replicate this behaviour. Rather than 'footballizing' an idea, you can apply your expert lens - the unique way in which you see the world based on your expertise within a niche field - and 'accountantize', 'lawerize', 'surveyorize' the same idea. Indeed many people may pay for your expert opinion around a piece of regulation, news, or update to a marketplace.

You can apply this same mindset to creating content. As an industry expert, rather than relying on industry publications, or niche announcements which may be few and far between in some service-lines, look for opportunities to draw on more generic news for inspiration.
