"Evita lo extravagante y céntrate en los fundamentos."

Simplified Meaning:

When people say to focus on the fundamentals, they mean you should concentrate on the basic, important things rather than chasing after what's trendy or flashy. Imagine a student learning to play the piano. It's more valuable for them to practice their scales and basic songs well than to skip ahead to showy pieces that might sound impressive but they cannot play properly. In sports, a basketball player who spends time on basic dribbling and shooting techniques will perform better in games than one who only practices fancy tricks. In your daily life, this advice suggests sticking with what really matters. For example, to be successful at work, you should focus on being punctual, meeting deadlines, and communicating clearly rather than trying to impress your boss with overly ambitious ideas you can't follow through on. By mastering the essentials, you'll build a strong foundation for future success.
