It's normal to feel inadequate as a Data Analyst.

I get envious when I see others:
- landing roles at FAANG companies
- building complex ML models
- earning multi six-figure salaries

But
- My goals aren't tech giant focused
- I'm happy storytelling with data
- Compensation isn't my only metric

How to embrace Excel as a data analyst:

Automate more. Validate more. Visualize more. Structure more. Document more. Question more.

Copy-paste less. Assume less. Overcomplicate less. Ignore errors less. Work manually less. Rush less.

Excel isn't about knowing every function; it's about clarity.

Avoid the "Learning Illusion" in Data Analytics

It's a common trap for data analysts.

Here's what it looks like:

But you never apply these skills.

Stop chasing new tools. Start solving problems.

What if uncertainty is our biggest advantage?
Uncertainty is everywhere.
It is during our darkest moments that we must focus to see the light.” -Aristotle Onassis
Those most uncertain times cause me to look toward the light.
Uncertainty isn't the enemy - it's the catalyst.

You don't need to master Power Query before building your first dashboard.
Bad advice:
"Learn more Excel before building anything."
Good advice:
"Build something useful with the Excel you already know."
Start with SUM, AVERAGE, and basic charts. You'll learn advanced features when you need them.

Why did the SQL query go to therapy?

It had too many JOINs and couldn’t find itself.

*No self JOINs allowed (this isn't a SQL interview test)!
