When I first started coding professionally, I wrote what "worked." But I didn’t write what could last.

That changed when I discovered SOLID.

🔍 A Quick Breakdown
🔹 S - Single Responsibility: Every class should only do one thing. Keeps your code lean and readable.

🔹 O - Open/Closed: Extend it? Yes. Modify it? No.

🔹 L - Liskov Substitution: Subtypes should behave like their parents.

🔹 I - Interface Segregation: Don’t make classes implement what they don’t use.

🔹 D - Dependency Inversion: Depend on abstractions, not concrete things.

💬 My Tip?
If you ever feel like your code is getting “too messy,” revisit SOLID. It's not just for architects—it’s for everyone who writes code that grows.
