You are right there! To become an Emacs expert probably requires 24 hour per day gym visitsThere is soooo ...... much to learn. You can only develop those 'muscles' by regular exercise.
I just learn it at my own pace, based on goals (1. agenda/todo management, 2. visual knowledge base) using mainly Org-mode, Org-Roam + Org-Roam-UI.
What an incredible piece of software!
