For a traditional career reading your horoscope is not difficult. You have Venus in the first house, and it is the one obvious significator of your career if you care to have one. Venus rules the 10th house.
Venus is also in mutual reception with both the Sun and Mercury. The Sun is always the natural significator of career, but in this case is fallen, in the third house and afflicted by Mars. The reception will not help it too much. This is probably why you cannot see an obvious career path. Mercury is in better condition being in its triplicity. It has led you to study astrology and I am sure you know other subjects.
The Moon is the tripicity ruler of the 10th house as well as exaltation ruler. In the 8th house it may take some time to get moving, but it does have strength there. Also it is in Hayz and with the ascending node. This is favorable for the Moon. Both the Moon and Venus behold the 10th house. Mars sextile Jupiter in the same degree should assist you along the way as these are both strong planets and in fortunate houses.
So what does Venus do: artist, entertainer, florist, interior decorator, jeweler, musician, tailor, clothing, hotels, theatres, amusement parks, places that serve food and drink and all things especially produced for women. In addition the Moon rules all maritime occupations, commodities, supermarkets and places that provide provisions and all the general stuff people need. And natives with Leo rising often are promoted to positions of authority and management. They well could become politicians.
