It's cool don't worry, I'll answer them all.
Not currently, but I have performed in a band numerous times (3...), and I used to do some acting thing when I was 10-12, but I dropped that because I lost interest and I probably wasn't that great anyway. I just love being on a stage though and prancing around whilst holding an instrument.. It's great.
As far as I know it's optional at my college, but I'm doing it anyway so it doesn't matter to me.
I don't have a career plan... I don't even want to go to college. If I could have things my way, I'd be working right now, saving up to travel the world. But it looks like I'm still going to be able to do that, I'll just be working in a part-time job. Honestly, the things I would do just to be able to tour in a band and travel the world...
These guys are living the life right now. They're massive in their scene, but hardly known to the majority of people. That video just gets me stoked on life. That's what I want to do. In regards to education, I have no clue. I just took two subjects I enjoy (Maths and German) and two subjects that I'm interested in (Psychology and Sociology). I wouldn't mind doing a degree in Criminology... But apart from that, I really don't know.
I don't know what that is, but I guess if your enrichment is somewhat related to your chosen career path then it will give you an upper-hand.
Sorry for the essay, but you asked.
