***Remember: The Sign modifies how the Planet will express itself. The House placement is where the Planet will express itself.
For instance, the Sun in Scorpio has the drive to succeed, and often has extracurricular activities that take it up a notch. There is a relentless effort that Scorpio puts into what they want to achieve. Here the vitality and potential to integrate one’s various talents and abilities is definitely impacted.
If the Sun is in the Seventh House for example, partnership and other people in general will play a large part in acquiring a sense of self. Should the Sun be afflicted in this domicile, then take care not to be overly influenced by others in determining who YOU are. An afflicted Sun generally indicates that it is either in its Detriment, (Aquarius), or in its Fall, (Libra).
On the other hand, a strongly placed Sun in the First House, leaves little room for anyone else! Life is completely your show—you are the producer and director (Capricorn), writer (Gemini), and of course, the star (Leo!). A strong Sun is usually either in its Dignity, (Leo), or in its Exaltation, (Aries).
Our Sun can also indicate where we are most likely to find men who play important roles in our lives. Should the Sun occupy the Ninth House for example, the individual is likely to meet men in educational capacities. Foreign men or men met while traveling abroad may also be highly significant to us. This would be especially the case if the Sun were in Sagittarius in the Ninth or in strong aspect to Jupiter from this position. The Sun in the Sixth House would put us in contact with men in work-oriented settings; doctors as well as the Sixth is the house of health. If the Sun were well placed here with a Trine or Sextile to Saturn, then such men would tend to be authority figures helpful to our success and well-being.
