I was a university teacher for the best part of twenty years (and for the most part, I loved it); the idea that people were prepared to pay me for talking about (researching, writing about, thinking about) stuff that really interested me - stuff I would talk about in the pub or coffee shop anyway - was an extraordinarily civilised concept.@VulchR, thank you so much for your advice, it's truly helpful! I mean I'll have to see what happens, but this is all good advice to live by! I just want to feel very prepared for the real world, you know what I mean?
@Scepticalscribe, mind me asking what you used to teach? I'm just curious.
And history has been an abiding passion (or interest) of mine since childhood (hence @VulchR's advice to "find your passion", and my observations to you about trying to find out what interests you; it helps to be captivated by, intellectually intrigued by, what you have chosen to study), while I developed a fascination with politics (which is really history in the present tense, to a certain extent) in my early to mid teens, several years before I started university.
