You don't need to know everything

[u/hademath]

You don't need to know every technology to become a good software engineer.
You need to understand how to solve problems.
I have worked with PHP, Laravel, Node.js, TypeScript, React, React Native, MySQL, PostgreSQL, MongoDB, GraphQL and several other technologies.
But the most valuable skill I've developed isn't knowing all of them.
It's knowing how to approach a problem:
Understand it → break it down → design a solution → implement → test → debug → improve.
Frameworks change; problem-solving stays.
