Wow, that's a pretty great ambition you've got there Daichi!
My goal or life ambition is pretty vague to be honest. I know I want to be in a position where I am helping people, this is vital to me. And when I say helping, I mean in a very direct and tangible way, working with people. This is essential for me, and I would like to be able to make a living doing so. I think I actually do (or more precisely-will) have a lot to offer. I could actually be more specific with myself about what I could do, but I don't think that would be a particularly helpful right now, I think it's better for me just to go along the path just because I know that it's good for me, rather than thinking about making a living off of it before that's even realistic.
So yeah I also want to study Japanese at university. To be honest, I don't even know how this part fit's into some grand scheme, I'm just doing it because it interests me purely and simply. I've studied different things in the past that were more vocational but which my heart was never in, so it never went well. That's not to say I'm not constantly thinking about how a qualification in Japanese could be of use to me, as I am every day. It's just I'm following my slightly irrational gut feeling with this, more than anything else. I just don't care about what anyone thinks anymore lol.
So yeah, ultimately I would like to combine my fairly distinctive skillset together to provide a service which will be of benefit to many people.
