I felt this way too until I realized that what I was really experiencing was that my desire to explore outside of my comfort zone had lessened with age.
Have you jumped into silent films? Buster Keaton?
Have you explored European Atmospheric Cinema? Jean-Luc Godard?
Art House? Non-Kurosawa Japanese films? Pre-Bollywood Indian films?
In the past, when confronted with questions like that, I would reply with a statement akin to: "Yeah, but that's not what interests me!"
And the lesson I needed to learn about myself was contained within those— my own —words.
