TSR is honestly part of the problem. Just look at their article guide:
"Think about what really does interest you. If you walk into a Library, what subjects do you gravitate to? What really interests, fascinates and enthuses you? This bit is actually far more important than focusing on what job it might or might not lead to. Does that surprise you?"
No, no, no and once again no. This is pointless advice. I'm interested in Russian history and masturbating but these degrees won't get me anywhere in life. Your primary concern should be what kind of career you wish to take out as a result of your degree.
People will look at this advice and realise that they like History of Art, they pay 27 000 for the Uni and 13 000 for transport, food, rent and whatever else and they just plunged themselves into one twentieth of a million pounds of debt to do a degree that is useless to almost all employers in this country and the chances of paying off that debt are nil to nil.
Honestly, terrible advice. Just because you like something doesn't mean you should pursue it as a career. If you like something it is YOUR hobby. People are not interested in YOUR hobbies, they want THEIR products/services. If you are not able to produce what the economy or society wants, you are useless in the labour market.
So treat it as a hobby. Not a career.
