Was there nothing from school that was useful? Did you learn to read and write, how to work as a group, or anything indirectly related to your current career?
I learned outside of school to read and write. Even how to work as a group from active social activities outside of school. Group activities in school didn't promote real strengths because the activities could have been done alone. Yet, I succeeded as a person who could work as a group by the strengths learned outside of school in social activities.
I'm a software developer who was self taught online. All social skills with others at work were as stated developed from social experiences outside school. Forums or even reddit helped me progress in writing. I think school isn't necessary if motivated and the field of interest doesn't require legal obligations to meet by some degree or specialist program. The education system is arguably similar to any other capitalist entity and desiring society to feel it's needed or required. It's a real shame because it's a debt machine in a poor economy where the previous generation didn't need a degree and could get a home in their name young.
