You can't be angsty all day or else it becomes a sort of pale angst.
This quote highlights the importance of emotional balance. Constantly dwelling on negative feelings like angst can diminish their intensity over time, leading to a dull or 'pale' version of the emotion. It suggests that expressing or experiencing strong emotions in moderation is essential for maintaining their authenticity and preventing emotional fatigue. Often, allowing oneself periods of vulnerability or emotion can help keep feelings fresh and genuine, rather than letting them fade into something less meaningful.
