Since Career or regular work takes majority part of our life which allows us to earn our income for foods, living, survival and ability to have the resources for all sort of enjoyment in life as well as supporting one's family and offspring. A Career reading pretty much is the entire chart.
The MC Leo, Sun Aries, exalted placed in his home 5th house. Trine Moon in and Saturn Rx in Sagittarius, square Uranus Rx, Mars and Neptune. This Sun is not necessary deluded as he is well aspected by Saturn in 2nd house, secondly, Neptune is in the sign of reality and maturity, endurance Capricorn. I see that as good balance.
Drug addiction will need a lot more analysis and doesn't simply apply to each individual with Neptune square natal planet. Square only means tension, but tension is awareness in our consciousness, an addict will need to have lack of awareness to start with for becoming an addict.
Square is tension of energy, which is frustrated and looking to be released like boiling water trying to escape the kattle as stream but tightly kept inside the kattle. Trine or sextile is the channel of positive expression which is Mars trine North node and Venus in wider orbs. It is about the 6th house, the things one do regularly each day. Mars also rules 6th house, Mars is exalted, very well self controlled, structural, followed the rules, mature and responsible Mars. He is like a General in army. Your diet and health habit may also be very well managed like in military style. Mars conjunct Neptune is not tight enough. But it is also about the Creativity of Sun and 5th house in Pisces and the link to the 6th house of daily matter and health. Capricorn is also strict and restrict any wrongly behavior, I don't think there is any addictive behavior. North node in the 6th house, meaning a life mission of learning about the practical matters in daily life.
In this case, Neptune is placed in 2nd house, that will be matter related to uncertainty about self value, talent, and poor management of financial matter, but not at the worse case as I said Neptune in a realistic sign.
Neptune rules 5th house, enhances one's artistic creativity but with a risk of disappointment in regard to sex, children and romantic relationship or simply like the dreamy type of girl and extreme romantic when in love. Since Neptune in the sign of Capricorn, it is unlikely that it will really gone out of control and relationship usually come late and or long lasting. Neptune in Capricorn actually describes the style of artistic expression and what turns you on sexually. Note that Mercury Rx in the 5th also rules over 8th house.
Venus in the 6th, daily works and routines related to the Venus in Aries, combine with Neptune in Capricorn ruler of 5th. Aries and Capricorn are the r&b, hip-hop, old school etc music matching with the information you provided. Capricorn is a sign of authority, you would be quite well respected by others for your creative works, I guess. Capricorn is a sign of structure and music and bates are structure the bone and frame of all songs.
This Neptune sextile Pluto Rx on your ascendant, the mini grand trine that I mentioned before Neptune, Pluto Rx and Jupiter, are the focus of the 2nd house. This configuration is your talent especially Jupiter being the ruler of 2nd house. Jupiter sextile Neptune as being ruled by Neptune in modern rulership but Jupiter as the final dispositor.
Once again, Uranus Rx is he ruler of the 4th placed in 2nd house, just like the ruler of 4th house Jupiter, Neptune placed in 2nd, and Jupiter the ruler of the 2nd placed in 4th. Many repetitive messages about income and home.
One very possible difficult of your 10th house is Sun quincunx your MC, the ruler of MC is in disharmony with his own ruling house. Me and you we don't get along well but we have to since we are longing for each other at the same time. This is your challenge. That will also be related to your own public image and social status.
I am waiting to see your chart with progressions. I am guessing at the moment your progressed 2nd house is in Capricorn, progressed AC is in Sagittarius, progressed would be in Taurus or Gemini. I will look further. See what I wrote above first.
