You have probably seen ads promising a data analyst career in three months. The honest answer is that it takes most people six to twelve months of steady work, not a weekend sprint.
The core skills are manageable: Excel or Google Sheets, SQL, and one visualization tool like Tableau or Power BI. Add a little statistics and you have the foundation.
The real time sink is practice. You need to work through messy datasets, write queries until they are second nature, and build a couple of portfolio dashboards that tell a story.
Start with SQL, because it is the skill every data job interviews on. Then learn one tool deeply rather than five tools shallowly. Six months of focused practice beats a year of scattered tutorials every time.
