Don't listen to what some ignorant people are saying about doing one you purely enjoy.
You're not paying £9000 + per year to have fun.
I'm going to be blunt here. Don't get it twisted. University is not about having a laugh and doing what you 'enjoy'. University is about getting a degree and acquiring the skills you need to get a ****ing job afterwards.
Some people make the mistake of thinking they're still 13 year olds when they apply to university. You dont pick university choices based on how much fun you're going to have or how many nap times or playdo you get to play with.
You need to grow up and make a mature decision based on forethought and intelligence.
You're only going to be in university for 3/4 years. Then what? Where will you live? What will you be doing to make money? Will you have a job?
There's a difference between a hobby and an occupation. What do you want to be after you graduate. An artist?
Even so, you dont need a degree in art to do that. With a degree in audiology you can still become an artist, you'll have access to a wider range of career options. But with a degree in art, well...it wont get you much.
You dont need an art degree to be an artist. just like how a degree in journalism is irrelevant because most journalists have degrees in subjects like history, english, law etc. There will always be art societies and opportunities to further your love and study of art. There's nothing you could learn in an art degree that you cant learn with other resources, online, short courses.
I myself attend regular life-drawing sessions, am a member of many art societies, philosophy societies, poetry societies, i'm a grade 8 pianist and attend a chess club once a week. That doesn't mean i'd waste 3 or 4 years of my life getting a degree in poetry, piano playing or chess. I'll be studying medicine because i genuinely enjoy the prospect of it, i love the vocation and though i know its a lot of hard work and wont be as 'enjoyable' as studying piano at a music conservatoire, i'll have a secure future.
most importantly i'll make a useful contribution to society with my vocation. being a doctor, surgeon will mean changing lives, having such an impact.
the most useful career a degree in art will get you is an art teacher in a secondary school.
even if you did become a famous artist, your art degree will be irrelevant as most of the world's famous artists did not need to study art at university.
You're going to have over £27000 worth of university dept, not including student loans.
What kind of lifestyle do you want to have after you graduate? You need a job that's going to support your plans.
You need a place to live and you're going to need a job to pay rent and support yourself. Unless you're going to be one of those 30 year olds that still live with their parents because they couldnt be bothered to get a useful degree and make a good living.
Don't "do what you enjoy", do what is going to get you a ****ing job so you're not living off welfare for the rest of your life.
For a lot of people, what they enjoy and what is going to give them a secure future are the same thing, however unfortunately thats not always the case and you need to be a foreward thinker.
University isn't about making short term decisions, its about long term goals. what you do now may literally determine what course your life will take.
