Wow~ This lecture hit me like a revelation;; I never knew design had such clear concepts and principles~ I'd recommend watching this before learning any tools~ It seems to give you an analytical perspective on why things look good~ The practical examples included make it even more useful~ Of course, it'll take practice to get comfortable with it😊😊 There are many lectures on Inflearn that teach tool functions, but theory lectures that establish design fundamentals like this are truly rare! If you're a design beginner, I strongly recommend watching this video before learning any tools~ Good~
