What skills should someone learn before touching Power BI?
I keep seeing people jump straight into dashboards, but I think the real advantage comes from the basics first:
- Excel
- SQL
- data cleaning
- basic statistics
- data modeling
- visualization principles
Power BI is the tool. The bigger skill is understanding the data and turning it into something useful for business decisions.
For people already working with Power BI, what skill helped you the most early on?
