Engineering (The Real-World Version)

Hazardous-area and electrical engineering, explained the way it actually works on site — not the way the textbook pretends it does. If ATEX is your world, start with the hazardous-area guides.

Here are a few principles that make life easier:

  • Learn by Doing — University gives you theory. The job gives you the messy version that actually matters.
  • Ask Questions Early — Guessing is how mistakes happen. Asking is how you avoid them.
  • Slow Down — Rushing leads to errors. A few extra minutes checking drawings, numbers, and requirements can save hours later.
  • Own Your Mistakes — Engineers don’t become good by avoiding mistakes. They become good by fixing them and understanding why they happened.
  • Communicate Clearly — Most engineering problems start with miscommunication. Clear writing, clear emails, clear questions save you more time than any tool.

Investing (Without Feeling Like an Idiot)

Most Popular Investing Post!

A separate, more personal strand. I track a real-money investing challenge every month and share what works and what doesn’t — including the losses. If you’ve ever opened a trading or investing app and thought, “I have no idea what I’m doing” — you’re exactly who I write for.

So, where do you start? Here are a few simple ideas:

  • Learn the Basics — Read up on investing, personal finance, and how markets roughly work.
  • Start Small — Even a few pounds a month is enough to build the habit.
  • Think Long-Term — Investing isn’t a get-rich-quick scheme. The goal is to build wealth over time.
  • Expect Mistakes — You’ll mess up. That’s fine. The goal is to learn, not to be perfect.
