Hello,

Interior design has a component called psychology.

The majority of interior design courses combine psychology with design because the two cannot be thought of as separate disciplines.

Before beginning to develop anything, you must first comprehend the foundational concepts of the same. Designing without taking psychology and human behaviour patterns into consideration would only result in a lifeless, more artistic final product devoid of any real personality and useful functionality.

I would advise starting with the principles of psychology, particularly in the context of space and ergonomics, then alternating this with the designing bit if you're hoping to learn it individually from YouTube.

The application-based approach will undoubtedly speed up your learning and understanding of the ideas.

Thank You
