Salima: Nearly everyone in the U.S. who has a decent aptitude and is willing to work hard can find a job they enjoy at least somewhat. There is a lot of support for hardworking students from underprivileged backgrounds who want to go to a decent university, and there are many many quality universities in the U.S. Most intelligent college educated people I know have a job they enjoy at least a little bit. That being said, you might have to get more education than the average bear and really teach yourself difficult skills, but if you are smart and hardworking it will most likely happen.
On the other hand, I know a guy whos brother went to college for english, but had been working with computers all of his life and now is a head engeneer who works in high level software engineering. No formal educaiton in the subject whatsoever, yet he has an unusual aptitude for the field and is exceptionally bright. The thing is though, he worked, hard, to get into the psotion he has. He had to show that he had a great aptitude he had developed through years of self teaching and the drifve to apply it.
Now, if you go through college with no passion for anything, get a cake degree and then get a decent paying job that you hate: that is really your fault. I suppose it is possible to never have found anything whatsoever in life that you have some passion for, but it seems unlikely (especially if you are in college and have any amount of free time whatsoever) unless you are a total dullard.
That being said, some people do get screwed over now and then, but most of them recover.
Now, as far as the complaints of Yogi DMT:
Man, I hated highschool with a passion! However, I learned on my own, I practiced music and art and read what I wanted to. I did not work very hard in highschool, I got a 3.0 GPA which is far from stellar but I scored very well on my SAT and got into a decent school. All of the homwork I did was done during the morning it was due and a lot of it was never handed in at all or was late and points were deducted.
I thought that highschool was a major waste of time, I wanted to be working on composing music and doing art or philosophy. I wanted to study subjects that interested me. I did have a few points that made me dislike school: I was advanced in math and the sciences (I knew a good amount of algebra in 5th grade and was really into astronomy) when I was younger but was let down during middle school when I was basically reviewing what I already knew and lost all my passion for learning math (I hadn't yet made the realization that learning math and school do not have to go hand in hand).
All I can say is that you should tough it out until you get to college. Then you can study anything that interests you. Try to look for a college that is strong in your areas of interest either by using the US news and work report rankings (if they have a strong phd program, they will usually have a very good undergrad program) if your interests are in the hard or social sciences or if you are into art/music look at who is teaching there. If they are well established musicians/artists, that is a great school. If they have never played a show/only showed their work in the "faculty gallery"(or something equally hokey), watch out.
If you do really well in highschool, you could try to apply to Brown, where no gen eds are required, or you could look into schools with more flexible gen ed requirements like ones where you can sub in higher level (more interesting, automatically) courses for gen eds.
That being said:I am almost certain that the only meaningful conversation you would have with a Harvard prof. would be about scheduling your next semester. Once you can read their research papers, understand them fully, and have a well thought out objection or a novel comentary prepared, then go ahead and shoot one of them an email. If your ideas are good they might keep up a dialogue with you (especially if they have a very narrow subfield without many colleagues to talk to) and then you could work out the possibility of doing a PHD thesis under them (if they have enough clout in their department to get you on) because you would clearly be up to date on current research in the area.
In the meantime, be happy with the MIT opencourseware....
