Looking back, I was right to think that way because my entire career has been built on things I taught myself via those hobbies and interests. Not even indirectly. Completely directly linked.
Even thinking objectively about the meta skills that “homework” may teach you, I still think it has accounted for 5-10% of my useful professional/life skills vs my own adolescent interests (programming, electronics, music production and entrepreneurial stuff) which I peg at 90-95%.
