Being an astrologer - I'm going to say the answer can be found if you look at your Astrological Chart. A person's Astrological Chart is determined by the exact time they were born and it reveals where all of the planets were living at that time. These placements say a lot about your personality as well as the things that you would excel at - as well as be challenged in.
The easiest way to hear about your chart is to visit an astrologer - but if you don't have the means to do so don't fret. You can easily run a chart on lots of free astrology websites on the net. All you need is your birth date/time and place of birth to do so.
In regards to career matters, the place that you'd need to look to first in order to see what your best suited for would be a place in your chart called your Midheaven. This special spot has an astrological sign that rules over it and there are jobs/career paths associated with each sign.
As an example, my Midheaven is ruled over by the dark sign of Scorpio. Scorpio loves a good hunt and has natural investigative instincts which would make for a perfect scientist or someone who seeks answers. This characteristic is perfect for me as an astrologer because it allows me to dive deep into someone's chart to see what's going on! I'm constantly intrigued by the unknown and always seek answers. I've also seen this placement work very well with doctors, researchers, investigators, or people who love a good "hunt" and aren't happy until they find the answer they seek.
So if you're stuck on what you should do - the answers you are looking for are out there! My suggestion is to look at your astrology and I promise you'll be amazed by what you'll find ;-)
