At any time of your life, if someone asks you what you’re learning, the answer can’t be “nothing”. You can’t know everything there is to know, nor should you try to, but with our complex and fast-changing world, even in your niche, in your small world, there are things you don’t know and if you did, they might change the quality of your life.
Not learning is a lesson in itself (when you dig deep). It shows what you value at this very moment.
