[DeathStorm]

This is my first topic here. Although I initially thought that it might fit in the "Character & Contribution" sub-forum, I expect that content-wise I'm looking for more short-term, practical answers (probably organizing and time management related), which is why I'm posting it here.

I already browsed a bit on other topics of the forum and noticed that many members are in my same age range (early twenties), so it's possible that my questions have crossed other minds as well.

The post is very long, so for those who don't want to read the whole story, I will summarize the central question:
"What are the practical and self-organizational behaviors required to specialize very well at something, and at the same time be able to train your other talents to a professionally relevant level (and not just hobbies)?"

I would obviously be most grateful if someone could give advice that is specific to my situation and my specific goals, but I welcome and appreciate your time for any answer.

Some quick facts: I'm 20, starting my second year at undergraduate university studies, have mixed origins and [maybe due to that: different countries, different schools, constant change to different international systems] had an unusual education, growth and coming of age - which might have contributed to the fact that I feel a great sense of both passion and connection to so many different fields in life. (It's just my opinion. I'm not a psychologist nor a geneticist, but I try to complete my picture of why I'm somewhat different from many of the people I have met in my life...)

When I was finishing my secondary education two years ago - a period during which I was already deeply exploring all possible options about my future career, studies, etc. - I was probably in one of the worst periods of my life because I felt confident about choosing virtually any degree or future profession (including artistic and music ones). I had a great deal of counseling in which all kinds of people opened my eyes about how it's difficult to succeed in today's world without specializing in one and only one area.
(I further understood how true this is as soon as I started my first year at university and learned more about how professional regulation works...)

I'm not inherently a careerist, but I want to develop myself and my talents in order to be most useful as possible to the world.
So the first thing I did before choosing my university degree (in case you don't know, in most European universities, you must state your "major" right at the beginning) was to sort my spontaneous interests from the talents at which I already had some relevant experience - and also fields at which I thought that I had a "competitive advantage" over other people.
My intention was to find a career path (or paths) in which my different talents would be useful at the same time, thus would also force me to keep learning and working at them, beyond the scope of my primary profession.

You might find this weird, but as a child I dreamed of having a different job for each day of the week. And my work experiences as a high school student somehow gave me the impression that I could realize that dream and become a professional jack-of-all-trades!
Just a few examples...
As I'm of different origins, I am naturally multilingual in several languages... and contacts allowed me to work as an interpreter and tour guide several times of the year.
But under normal circumstances, interpreters need professional training in translating methods prior to work experience + certificates, state exams, etc.
So for instance I pursued a degree in Astrophysics and applied for a job as an interpreter at the U.N. I obviously cannot expect the same kindness and luck that I had with my contacts :P
There was a time in which I also had a knack for web design, and - again through contacts and word of mouth - I earned quite a lot by creating websites. I thought that web design might have been a road to safe money even if I chose a degree unrelated to computers or art, but even this field is seeing a surge of specialization (5 years ago there were no "B.Sc. Web Design" courses at university...) in addition to an increased slope of technological innovation (post-Ajax, Web 3.0?).
Same applies for many other fields that I once perceived to be "transferable skills", yet they are also caught up by new standards and professional regulations.
To add a few more: I worked in audio technology, tourism B2B, and public relations - and I enjoyed all of them.
Plus there are other fields in which I was deeply involved but that doesn't really count as work experience (acting for several troupes, acting+singing+dancing at musicals, "voluntary work" - yeah I know it's a paradox, but that's what students write in their CVs to impress future employers :P).

So, I finally chose to major in Economics & Management (BTW a subject which keeps reminding me of "specialization"), my goal being to do something useful for countries in development or even enter some field of international diplomacy, or business (using my main skill of multilinguism) - and at the same time try to develop my other skills.

The first year was disastrous. I always had good marks at school, despite the constant changes, but I think that this was a bit too challenging for my time and organizational skills.
I think that I was focusing more on the "other skills" rather than on what I was supposed to study at university. I was commissioned to compose a soundtrack for a local documentaries, did B2B partnerships for a company abroad, had to manage two websites, helped foreign workers adapt themselves to this country, and started attending a course for a new dance style... in addition to the work in a few student representative bodies at the university itself.
I enjoyed it in the beginning but once I saw how my grades were declining...
I quit almost everything, except for university.

So this is why I'm here, a few weeks before starting the second year at university, looking for some realistic advice on what I could do with my jack-of-all-trades attitude without compromising anything.

I told myself that at least for these two years I'll try focusing only on university studies. And maybe later try to sequentially catch up with the other skills (i.e. one thing at a time).

What do you think?
Sorry for the bloggy-ness of this post, but I needed to say everything.

If you know any, could you suggest me some non-stereotypical books or links that address my specific issue?

Thank You.
