My experience as a schooled child now adult is that school alone did not give me skills to chafe under menial work with marching hours. School is a practice ground, but not the life-skills teacher. Acceptance of price to pay for a goal I already decided I wanted is the most helpful for me, and I learned that mental trick on youtube.
As for “high powered careers”: no office job I’ve ever had has a curriculum to get promoted as part of its duties. Conferences, books, videos, mentors, and certification courses for the coveted ‘perennial learner’ employee all sound much more like an adult engaging in the non-linear style of learning described here. As one business owner put it “you make yourself valuable after 5.” Is a person studying something and putting in the work, or watching Netflix? Intrinsic motivation carries the self-ship out of Routine Harbor.
