Learn How to Learn #

You can find almost anything online, especially if your goal is to learn a new programming language.

However, knowing how to write code doesn’t mean you’ve mastered it.

You must question yourself.

The challenge is that you also need to be skilled—and therefore confident enough—to deliver valuable work.

Tools change; core concepts endure.

That’s why paradigms like OOP help developers learn new languages faster.

Different syntaxes and operators exist, but you’ll often encounter similar structures and loops.

You’ll also reduce the risk of poor outcomes, such as misconfigurations, misuse, and overly complex tooling.
