I'm trying to plan a path toward becoming a data analyst and I'm unsure what to prioritize. Should I focus first on programming, SQL, or dashboard and visualization tools such as Power BI? I've completed a few introductory SQL courses but still don't feel confident, so I'd also like to know how people judge whether their SQL skills are strong enough for entry-level work.

It’s not really an either-or decision; it’s more about the order. Begin with SQL, while learning basic concepts such as averages, spread, distributions, and data interpretation in parallel. Then add a dashboard tool and Python as your projects and job goals require them.
The best sequence also depends on the job market where you live. Look at several local analyst job postings and identify the tools employers repeatedly request. That will help you decide whether to emphasize Power BI, Tableau, Python, or another skill after learning the core SQL fundamentals.
SQL is essential for data analysis because most business data is stored in relational databases. After that, learn basic statistics and dashboarding, then add Python for automation, deeper analysis, and larger datasets. Python is generally the more versatile choice compared with R, although either can be useful depending on the role.
You can usually build confidence by practicing joins, aggregations, subqueries, CTEs, window functions, and data-cleaning tasks on realistic datasets. Being able to solve common business questions is more useful than simply finishing courses.
Start with SQL and a visualization tool such as Power BI or Tableau. Those are usually the most immediately useful skills for analyst roles. Python can come afterward once you have a reason to use it.
How do you know when your SQL is proficient enough? I’ve taken a few courses, but I still don’t feel like I know very much.
