You should learn things that don’t change.

Every day, I learn new things in programming, tech, and life. I'm grateful for everyone who teaches me something. Today's advice for learning is to understand that you should learn things that don’t change (quote from Jeff Bezos) and focus on fundamentals because they don’t change with time. If you are learning a programming language, what fundamentals should you learn and focus on? 

• Data Cleaning Code
• Algorithms 
• SOLID Principles 
• "OOP" Object-Oriented Programming 
• Design Patterns 
• Distributed Computing 
• System Design And more.

I hope for You Happy Learning
