Opinion pieces like this always strike me as more about their individual definition of the phrase.
To me "Be Yourself" doesn't meant to blurt out everything in your head it means don't try to be something you're not.
In my experience people can subconsciously pick up on authenticity and if you're trying to be something you're not you're just going to fall flat on your face.
To put it simply to be yourself is to always strive for genuine connections and goals which truly interest and excite you, in work, love or whatever
