Thanks, this is really helpful.
After following the second link I found a useful interview with Maria Gutierrez, a Costa Rican artist who is doing projects for charities to help with marketing and image and is considering a career in art dealing in order to earn to give. This interview demonstrates how there are many avenues you can follow to do good no matter your skill set.
As far as A-levels go, I think I will choose Product Design as a fairly broad subject I enjoy which could be carried forward as well as Maths as a useful skill, German as I am good at it and it opens up opportunities and either Art or Music as something I enjoy to drop later.
Thanks for your input, much appreciated.
Hi, thanks a lot, and good luck with your A-levels! I'll try to expose myself to as many different experiences and interests as possible and hope something positive sticks.
