Hi everyone, I'm dusting off this account to embrace my new role as a data teacher and founder of the DataSharp Academy.
With DSA, I aim to help people who work with data move from messy scripts and guesswork to clear, repeatable analyses in R.

⏰ Last chance to join my live online workshop R Fundamentals for Data Science.
We start on 26 January (4 full days, European time).
If you keep telling yourself you’ll “get serious with R later”, this is the time to actually do it. 🧵

Be honest: do you ever do “ostrich data analysis”? Avoiding your messy scripts and half-broken spreadsheets because opening them feels worse than not knowing.
Zozo has been there too. Time to stop hiding from your data. 🧵

Data will shape your career whether you like it or not. The real question is: are you in the driver’s seat, or a passenger watching other people’s scripts run and hoping they’re right? Zozo and I vote for taking the wheel. 🧵

Stop thinking data analysis is “not for you”. It can be. And it will be.
Every confident-looking data analyst once had no idea what they were doing – they just started, failed, and figured things out.

Most people only try to “get serious” about R when the deadline is already on fire – thesis due, paper rejected, project review next week.
That’s the worst possible moment to learn core skills. Data confidence is built before the crisis.

Everything works while you're in the workshop. 😎
But the weirdest bugs? They wait until you're alone to show up. 😵💫
That’s why all @DataSharp Academy workshops include 4 weeks of unlimited Q&A. Because learning shouldn’t stop when the Zoom call ends.

🎯 I’m always curious how people first got into R. Was it through plotting? Analysing data? A specific package?
What was the first thing that made you say, "How cool would it be if I knew some R?"
For that, I created a quick poll: www.linkedin.com/feed/update/...

If you started learning a new language today, you wouldn’t expect to debate politics next week.
Yet with R or data analysis, we often expect exactly that – instant fluency, no mistakes allowed.
Data skills are a language. They need time, repetition and gentle practice.

Still relying on Excel for your data analysis?
It’s fine for quick looks. But when you need clarity, reproducibility and scale, you’re working against the tool, not with it.
Your future self is asking you to upgrade. 🧵⬇️

Most R scripts look like we’ve been operating with boxing gloves on. 🥊
What if you wrote code like a surgeon instead — small, precise, deliberate changes that actually fix the problem?

Or already use AI… and waste hours debugging code you don’t really understand?
