When I got into data engineering, nobody handed me a map.
I learned the hard way — broken pipelines at 2am, dashboards that lied, "small" changes that detonated three teams over. Every lesson cost me something: a late night, an awkward standup, a number I couldn't explain to a stakeholder who'd already lost trust in the data.
So I started writing the lessons down. The ones that had nothing to do with tools or frameworks, and everything to do with how the job actually works once real systems, real deadlines, and real people are involved.
That list became The 10 Laws of Data Engineering — things like "Assumption is the mother of all data issues," "If it's not tested, it's just hope," and the one that took me longest to understand: trust is the final output. Nobody cares how elegant your code is if they don't trust the data.
I've packaged all ten into a clean, printable PDF you can keep next to your desk — a quick gut-check before you ship, and a reminder of what separates a pipeline that survives from one that surprises you.

I hope these laws help you prepare better, sidestep the traps that cost me so many late nights, and understand the why behind the work — not just the how.
