@Toluwalopemiade @vheeorji22 You welcome

@AskMichaelTaiwo his is the whole equation.
Most people want the result but are negotiating with the sacrifice required to reach it.
The math never lies.

@officialladi_T Excel. And I will die on this hill.
Every client has it. Every business runs on it. No installation, no licence drama, no IT approval needed.
The most underestimated tool in the room is always the one everyone assumes they already know

@iam_daniiell FILTER() entered the chat.
XLOOKUP finds one match. FILTER finds all of them and spills the results automatically.
The day I discovered this I went back and rebuilt three client reports from scratch.

@IAmAaronWill The first year is doing everything right and having nothing to show the people asking "so how is the business going?"
You keep going anyway.
That quietness is not failure. It is foundation.

[Arinze | Data & AI for Africa @data_chieff]

@DabereNnamani This is the part most analysts miss completely.
They spend 3 days perfecting colours and card layouts. Then hand over a dashboard the business cannot act on.
The best question I started asking before every build: "What decision changes if this number moves?"

[Arinze | Data & AI for Africa @data_chieff]

@ezekiel_aleke The moment I stopped treating data as a skill and started treating it as income everything changed.
Excel alone can get you your first client. Power BI gets you retained.
Take it seriously this year. The market is paying.

Data analyst interview be like:
Them: "Tell me about yourself" You: explains entire life story with pivot tables
Just be yourself. But make it SQL.

[Arinze | Data & AI for Africa @data_chieff]

The 4 SQL clauses that will solve 80% of your real work problems:
SELECT — pick your columns
WHERE — filter your rows
GROUP BY — summarize your data
ORDER BY — sort your results
Master these 4 before chasing anything else.

Nobody becomes a data analyst by watching tutorials.
They become one by opening a messy dataset at 11pm and refusing to close the laptop until it makes sense.
That stubbornness is the real skill.

@FortuneDataGuy Bro dropped this and kept scrolling like he didn't just shift someone's entire morning energy. Claiming every word. June is not playing with us.

@iam_Uchenna Good work compounds. They didn't move you they promoted you to where the future is being built. AI Centre of Excellence is where strategy gets decided before it reaches everyone else. You're early.

@veraherself And once you start, the next lesson reveals itself. Data skills are not a syllabus they're a breadcrumb trail. Follow the next crumb.

[Arinze | Data & AI for Africa @data_chieff]

@JA_Olaoye Spot on. Most beginners aren't lost they're just unconfirmed. They've consumed the content. They need someone to look at their work and say "yes, you're on the right track." That gap is where mentors make the most impact.

[Arinze | Data & AI for Africa @data_chieff]

@IAmAaronWill Comfort is just slow failure with a better aesthetic. The hunger that got you here won't maintain itself you have to choose it again every morning.

[Arinze | Data & AI for Africa @data_chieff]

@Tech_babby Honest take. Nobody has the full picture not the VCs, not the researchers, not the LinkedIn gurus. The only real edge right now is staying close to the tools and building reps. Confusion is the terrain. Navigate anyway.

[Arinze | Data & AI for Africa @data_chieff]

@ezekiel_aleke Somebody screenshot this and send it to everyone crying about not affording Udemy courses. Your free YouTube + daily practice will beat their paid certificate + zero reps every time.

[Arinze | Data & AI for Africa @data_chieff]

@officialladi_T The comments that sting the most usually come from people who never shipped anything. Keep building. Keep posting. The noise fades the work stays.

@vheeorji22 Looking back at my own journey, the biggest time-waster was learning in isolation no projects, no portfolio, no real data problems to solve. At PureQuery, the first thing I tell every student: learn with purpose. Every skill should connect to an output someone can see.
