Hi Littlecat,
Not all Leo Asc. are equally outgoing, extroverted personalities. You need to look at where the Sun (as the Sun rules Leo) is placed, sign wise, as that sign's energies will colour how that Sun expresses itself. Also, you need to see what aspects that Sun. And then have a look at the Moon.
I can already see very clearly why you call yourself "inhibited". The fact that your Sun in Pisces along with being in an aspect to Saturn is a big contributor to being inhibited. To add to that, your Moon, though in versatile and chatty Gem., is in an exact opposition to that Saturn as well. This makes it even more difficult for you to open up, esp. when you don't know the other party well. There is also an element of caution and discreetness involved.
As to your career path, Venus, ruler of your 10th house, is in Aquarius and Mars is close at hand to the MC. Venus also is in an aspect to Jup in Aries. You might not like a regular 9 to 5 behind the desk job, and require something that gives a bit of freedom and movement. Do things like photography, or even social serv. interest you?
