Take up automotive engineering. Learn all you can about modern systems and [...] You can always study and fiddle with carburetors and cam grinds in your spare time, but if you want to work on automobiles professionally, you've got to expand your horizons.
Thanks everyone, I guess in a few years it'll all be those stupid electric cars -_-
The point is not to be too specific, as there's many other interesting avenues that open up to electrics/electronics, from aviation to zoology, whereas the internal combustion engine doesn't support much more than automobiles, trucks, generators, small-engine equipment, light aircraft, and trains (which are changing over, too). You'll have to know more and more about the electronics of a car, as just about anything made in the past 20 years is increasingly electronic in nature, and only rising in usage.
In the end, do what you like; that's where you'll be happiest in life. I'm not the biggest electric car fanatic at all, but you've got to realize where the future is, if you want a competitive advantage. My advice is: A lot of life is about exploiting and using every competitive advantage you can legally find, but the best way to have a harmonious one is not to step on too many toes when doing so.
Other helpful advice, sort of along the automotive spectrum.
When I was 13 I wanted to be a Formula 1 driver....but then I realized nobody likes Americans.
The real reason is that Americans don't like F1 racing, but you could if you had a lot of money and a lot of talent in the right palce and the right time, although more money helps in the short-term. Many drivers just got lucky, and pursued their dream in the direction they wanted to take. If anything, being an American would probably be an advantage; most racing drivers in Europe likely dream of either F1 or WRC; in America, there's many different summits to climb in the world of motorsport. Formula One is
not the most famous mountain to scale from this viewpoint, which can distance oneself from the rest easily, if you have what it takes (see above).
Anyhow, been there (er, not really), dreamed that, so you really can't blame others for your lack of F1 participation. Although once a year, I still have that dream that Minardi or Arrows needs a driver, and calls me up on a Wednesday afternoon; life needs a little fantasy sometimes.
