I don't know about you, but I tried going to the university and studying something I was good at (Computer Engineering) and paid a lot more, instead of studying what I love (Arts). It was very depressing. So I gave up on Computer Engineering and started studying Licentiate in Visual Arts, and I'm loving it. But, as Erkka said, it's not a good idea to recklessly encourage people to just listen to their heart and follow their dreams, there's a realistic part too. But the decision is up to you, in the end no one can tell you what to do. You have to try, you'll put yourself at risk in both choices, and if one option fails, you can try another one, it's okay to do that.

Also, I think we are not made of 'careers'. Our jobs are not something hardwired into us, something that we can only choose once and it will be our work for the rest of our lives. No no, we humans are capable of doing many different things and learning new things too. I'm studying Arts, and my dream is to live somewhat like Erkka, work in a farm or a shop at the countryside, or something that I'm yet to discover.
