I’d practice thinking in terms of actions -> supporting data, not dashboards.
Take a public dataset and give yourself a fake prompt like: “Sales dropped 15%, what should we do?” Then think of possible actions and ask what data would justify each one.
Also, if an insight isn’t actionable and doesn’t create follow-up questions, ask: so what? If nobody would do anything differently because of that metric, I’d argue it’s not worth checking in the first place.
You don’t need industry experience for this. You’re practicing decision making, which is most of the “business thinking” people talk about.
The best way to develop it is, being the decision maker. Making a decision, and seeing the results in the following days / weeks.
That's why for an analytics person the best industries are the fast paced ones. Let's say you're working in a bank and making the loan decisions. You decided to issue a loan. So what? You'll see the outcome in the following years. 5 years later, you see if the money is back or not.
On the other hand, if you're the product manager of a mobile game, everything is much fast paced. You fail fast, and learn fast as well.
