6 Months on Substack: What I Built, Learned, and What Comes Next

A Honest Reflection on Writing, Building, and Finding Your Voice in a Crowded Space

6 months ago I started this Substack with a simple goal. I wanted a place to think in public. After 13 years in data science and analytics, most of my work lived inside private repos, internal dashboards, and conversations that never escaped the meeting room. I missed the clarity that comes from explaining ideas to people who are genuinely curious, not just waiting for the next sprint ticket.

I didn’t start with a grand strategy. No content calendar, no growth hacks. I started because I wanted to write about the gap between what people think data science is and what it actually looks like when you’re in it. The reasoning, the tradeoffs, the messy middle, the quiet decisions that shape real systems and rarely make it into blog posts.

I also wanted to slow down. The AI world moves fast, sometimes too fast, and writing forces me to choose what actually matters. It became a way to reconnect with my own expertise, to put into words the things I’ve learned over a decade of building, breaking, and fixing. So I published the first post. Then another. Now I’m looking back at six months of it.

The First Six Months in Numbers

Six months is long enough to see patterns. Around 15 posts published, just over 120 subscribers, engagement that is slow and steady. The numbers are small, I know. They are also honest.

Data science and AI are crowded spaces, and most content out there is optimized for speed and surface. I was not immune to that pull early on. My first posts leaned into AI topics because that is what felt urgent, what everything was pointing at. It took a few months and a few posts that did not quite feel like mine to figure out what I actually wanted to say. Somewhere along the way I found my way back to the thing I started this for: the practical, often unglamorous reality of working with data at a professional level. That drift and correction probably cost me some early momentum. It also gave me a clearer sense of direction than I would have had otherwise.

I write when I have something worth saying. I focus on insights from real work, the kind that take time to develop and do not compress well into a carousel. That choice leads to slower growth, but it tends to attract readers who stay. I am comfortable with that tradeoff.

The Break I Had to Take

Somewhere around month three, I stopped writing. Not because I ran out of ideas, but because life made it impossible to think about anything else. My mother has been fighting cancer, and I needed to be with her for a while, as I should have.

I am not sharing this for sympathy. I am sharing it because honest reflections on creative work should include the parts where it stops, and why. Writing requires a kind of mental availability that you cannot always guarantee. Sometimes the right move is to close the laptop and be somewhere else entirely. Things are more stable now. I came back when I was ready.

What I Learned in Six Months

The obvious answer is that I found my voice. The less obvious answer is that it took longer than I expected and I am still refining it. I know now that I want to write about data, the real work of it, not the hype. That clarity did not come from planning, it came from publishing things that felt slightly off until something finally felt right.

Time is a real constraint. I have no shortage of ideas but finding the hours to develop them properly is harder than I anticipated. Writing that reflects 13 years of experience does not come out in a sitting.

I also shared a tool I built, something I was genuinely proud of. The response was quiet. That used to be the kind of thing that would make me second guess whether any of this was worth it. Strangely, it did not. I think I am starting to separate the work from the reception, which feels like progress.

What I am still learning is how to share. Building things comes naturally to me. Putting them in front of people, talking about them without underselling or overthinking, that is the muscle I am actually developing here. Substack is teaching me that more than anything else.

And then there are the other writers. I spend time reading how people here structure their thinking, find their rhythm, express themselves. It is the best kind of learning, watching people do the real thing in real time, not a course or a framework, just someone figuring it out in public. I find that genuinely inspiring.

What I’m Working On Now

I build things. That has always been true, and Substack has not changed it, if anything it has given me more reason to connect the building to the writing.

Right now I am working on two projects. One is a fully automated weekly digest for a niche hobby community, a pipeline that aggregates content from writers across Substack, WordPress, Ghost, and Medium, organizes it, and ships a publication every Sunday without manual work. It is the kind of infrastructure problem I enjoy: unglamorous, quietly useful, and harder than it looks.

The other is a research intelligence pipeline that monitors AI sources daily and turns papers and blog posts into structured, actionable summaries. The same system can be configured for any domain. I am still validating whether there is real demand for it, which is its own kind of data problem. Both projects will feed back into this publication. That is the idea anyway.

What I Plan for the Next Six Months

More posts, more projects, more showing up. I want to write with the consistency that I have not quite managed in the first six months, and I want to build something that feels less like a publication and more like a community. A place where people who work with data seriously, not people chasing the hype, can exchange ideas, push back on each other, and learn from real experience. I also hope not to need another break. That one is not entirely in my hands, but things are more settled now and I intend to use that. The honest version of any plan at this stage is just: keep going. So that is what I am doing.

To everyone who stayed subscribed through the quiet months, through the gaps and the silences and the stretches where I was not even here to notice, thank you. It means a lot to me. I will try to be more consistent from here. Not a promise, just an intention, and a genuine one. And if things go the way I hope, I will be back in six months with another one of these posts to see how it all turned out.
