Different way of looking at things? It's not just university that did this for me but school too.
I went to a further grammar school that went independent when the local council started shutting grammar schools down. As a result it had to charge fees but it also offered full scholarships for bright local kids just the ones helped by grammars originally. The teaching was rigorous and aimed high, but the most important part was that they worked on developing the child to think critically. A different way of looking at things you could say.
One big influence read GCSE English teacher who woke my awareness and critical thought big time. Another was a guy who left school at 13, eventually got a job at my school as a caretaker and while working got his o levels and a levels. Even got a degree in English literature then teaching qualification. He then came back as a teacher at the school he started at as caretaker. When I joined the school he was 60+ and deputy head. He only taught what was called tumble then later on in our school career it became general studies a levels. The purpose of those classes were to round the child out. A scientist learns literature, music and art. A humanities or arts based student learnt science, computer programming, etc. We all had our educational gaps filled in.
