Libra and Aquarius aren’t good Signs for the Sun (my Sun is as well in Aquarius).
In Libra the Sun is said in its fall, and in Aquarius in its detriment: therefore in these two Signs the Sun is in bad zodiacal shape. But according to traditional astrology it isn’t necessarily connected to one’s personality, it depends on one’s whole natal chart.
For example, if the Sun is the ruler of the 10th House or in the 10th, it will symbolize particularly one’s career and a good name. If the Sun is in Libra or Aquarius Sign, therefore in bad zodiacal shape these things (one's career, honors) could be a bit difficult for the native (there are other factors to take into account, naturally).
In a more simple way, I think the Moon sign has a more important effect on one's personality, because the Moon is the natural significator of emotions.
Concerning my Sun Sign I don’t exactly hate it, but because it is in bad zodiacal state, unfortunately, it creates problems in my life, and I don’t like this of course. My Jupiter isn’t too bad, I hope that it helps a little bit.
