The 80/20 of learning to code: what to learn first (and what to skip)

Most beginner roadmaps are long. Too long. They list fifty technologies and leave you feeling behind before you start.

The Pareto principle (the 80/20 rule) suggests a different approach: a small share of what you learn tends to produce most of the results. Here is how I apply it to learning to code.

1. Pick one language and go deep
Switching languages every month feels like progress, but it isn't. One language, learned properly, teaches you variables, functions, data structures and debugging. Those carry over to everything else.

2. Learn how the web works
HTTP requests, HTML, CSS and a little JavaScript. Even if you never become a front-end developer, this explains most of what you will touch.

3. Use Git from day one
Not advanced Git. Just commit, branch, push and read a diff. It costs a weekend and you will use it every day for years.

4. Build small things and finish them
A tiny app that works teaches more than ten half-finished tutorials. Finish it, then improve it.

5. Learn to read errors
Most debugging is reading the message carefully and searching for the right words. Practise it on purpose.

6. Learn basic SQL
Data lives in databases. SELECT, JOIN, GROUP BY and indexes cover a surprising amount of real work.

What I would skip at the start
Chasing every new framework, memorising syntax you can look up, and collecting courses you will never finish.
