Building profitable internet businesses with SEO + data.

120-day journey: Zero → Data Analyst.

Building in public.

Day 9/120

Before today:

Open the file.
Loop through each row.
Split the values.
Process the data.

Today:

https://t.co/fUA9IQc5J6_csv("students.csv")
One line replaced all of that.

Now I understand why pandas is the standard library for data analysis in Python.

Day 8/120

Before today:

["Alice", 25, "Delhi"]

Today:

{
"name": "Alice",
"age": 25,
"city": "Delhi"
}

Same information.

Much easier to understand.

[Sagar Thakur @Sagar__019]

Day 8/120

Yesterday:

person[0]
Today:
person["name"]

That's what dictionaries taught me.

Same data.
Much clearer code.

One week into my 120-day challenge.

Here's what I've learned:

Skills come from practice, not from saying you're learning.

That's why I share every exercise, every mistake, and every improvement.

If you're interested in Python, SEO, or building products, let's connect.

@irbaazkadri Exactly. Memory reveals understanding, repetition turns knowledge into real skill.

Day 7/120,Week 1 Complete
Review day.

I rebuilt one exercise from each of the last 6 days from memory.

No notes.
No ChatGPT.
No copy-paste.

If I couldn't rebuild it,I hadn't actually learned it.

7 exercises completed.
A lot of syntax mistakes.
Every one fixed.

Week 1 done.

[Sagar Thakur @Sagar__019]

@siddharthwv That's the goal, building a life you don't need weekends to escape.

[Sagar Thakur @Sagar__019]

@_sgarbini AI speeds drafting, but clear thinking and editing still win today.

[Sagar Thakur @Sagar__019]

@StevenCravotta Know your customer first, everything else gets much easier afterward.

[Sagar Thakur @Sagar__019]

@levelsio That's exactly why I'm focusing on learning the fundamentals. AI changes fast, but the ability to build, think, and adapt doesn't go out of date.

[Sagar Thakur @Sagar__019]

@SalesPsych0 Building your own opportunity is a path worth considering. Even a small business can teach skills that last.

[Sagar Thakur @Sagar__019]

While learning Python, I'm also building:

• https://t.co/oMC6lDgG4E
• https://t.co/EcD8KNmvvp

Starting next week, I'll share the Search Console numbers, rankings, and experiments behind all three.
113 days to go.

[Sagar Thakur @Sagar__019]

Day 7

Review day.

I rebuilt one exercise from each previous day.

No notes.
No ChatGPT.
No copy-paste.

If I couldn't remember it, I hadn't actually learned it.

[Sagar Thakur @Sagar__019]

Loops answer:

"How do I repeat this?"

Functions answer:

"How do I organize this?"

Today was the first time I thought about how to structure my code, instead of just getting it to run.
