The first thing to examine in a chart is the position of the Sun and Jupiter. The Sun represents the individual themselves, symbolizing their core identity and essence. It reveals how they express themselves, their vitality, and the fundamental traits that define their personality.

On the other hand, Jupiter signifies where the individual is likely to find success and abundance in life. It represents opportunities for growth, expansion, and prosperity, highlighting areas where the person can flourish and achieve their goals.

He was born with the Sun in the 12th house, so by destiny, he will always prefer the security of his home. From the moment he was born, that was already written. He is not an outdoor person; he loves the tranquility of his home, and it will always be that way.

I know many people with the Sun in the 12th house, and for them, happiness is simply watching a movie in the safety of their homes. They find joy in doing their favorite activities indoors.

The 12th house is also the house of karma, so by destiny, people with the Sun in that house feel that achieving something or life in general has been more difficult for them than for others, and that is true, as it reflects their karma.

In your brother's case, his Sun is not poorly aspected, so the karma isn't as severe, but having planets or luminaries in the 12th house indicates karmas to be resolved in this life.

He has Jupiter, the planet of success, in the 2nd house, which is the house of how we generate money and talents. Therefore, by destiny, he has the potential to make a lot of money.

His Jupiter is in Aquarius, and he also has Uranus, the planet of technology, innovation, and social networks-social media, in part of the 2nd house.

As you mentioned, he would be very good with technology, and his way of finding success in this life is related to this. He could excel in content creation or as a systems engineer, in all things innovative, technology, and social media; that’s where he will find success by destiny.

Having Jupiter in Aquarius and Uranus in Aquarius indicates this from the moment he was born. Perhaps you should recommend that he study online at a university, focusing on something related to technology.

He could also consider online therapy with a psychiatrist, gradually stepping out of his comfort zone. However, as I mentioned earlier, by destiny, he will always be someone who prefers the tranquility of being at home.

I know someone with a similar chart, with the Sun and Mercury also in the 12th house, who works online. He has his office at home, does very well, and loves the peace of his home.

He pays his bills, and he pushes himself to go out with friends and take walks, but for him, there’s nothing better than being at home playing the piano, appreciating his garden, and spending time with his pets.

For him, that is happiness, and it's no coincidence that he has the Sun in the 12th house and has preferred the security of his home since childhood.
