Thank you for allowing to pass the personalized reading.
Here is my experience:
Astrology is ruled by the two Gurus, Jupiter, the Deva guru and Venus the Rakshasa Guru.
The second house is the house of voice and hence the house of prediction and astrology.
the people who have Jupiter sitting the second house or even better, aspecting the second house, are good at making predictions, it is considered as a gift from the Gods for an astrologer.
Similarly if Venus is sitting in or aspecting the second house, the person is good at speaking and making predictions.
If both Venus and Jupiter influence the second house, a person takes to astrology naturally, in fact it is believed that such people are born with the knowledge of astrology that they have carried forward to this life.
PS: I have seen this in the horoscopes of several astrologers.
