I agree, I always thought I wanted to do law, and managed to get onto a great course at uni so that's what I'm doing now. When you get to uni you realise how many different options there are, so now I'm even questioning if I want a career in law at all. That may sound really unnerving but it's actually refreshing to know that you can do so many things afterwards (even if I fail, which I worry about time). Trust me, you have not messed up your life. Go to uni, do your humanities degree, and worry about what you want to do a bit later. There really is no rush. Hope this helps xx
