A piece of paper does not encapsulate a person’s worth. University is one good way of enhancing your understanding and experience of this wonderful world, but there are many other ways.
I was very unhappy with the discipline and structure of school and did very badly – my A Levels were BEE. I lost my place to do law and scraped into Dundee on clearing to study History. In the free atmosphere of university I flourished and ended up with a First, as well as twice being President of the students union (and eventually became Rector of the university). My parents and friends were very upset the day my A Level results came out but I knew, even then, there were much more important things in life. I know it still more now.
Study what you enjoy, not what you think might pay. The economic world is changing so fast there are few safe bets anyway. But you are a wonderful, complex being, not just an economic agent. Experience life wherever it takes you. Everybody deserves love, and with patience you will find some. Nobody’s worth depends on bits of paper of any kind.
