No but I think its interesting to look at your natal chart and see what matches up. Its fun for me, I don't truly believe in it.
I'm capricorn sun, gemini moon, and I think cancer rising
I don't remember all the traits, to be honest. Some of them matched for me, some didn't. the whole natal chart makes it more complicated and not always accurate, but some ways it matches.
just by my sun sign alone? No, not much. I think capricorns are supposed to value social tradition and convention, be really into the "right" appearances, hard working and type a personality types, highly value family tradition, reserved, "great respect for authority", etc.
That isn't true for me at all. Only thing I wish were true would be the hard working thing. However, astrology does conveniently say that life and experiences can get in the way of what you're truly meant to be and your true personality. And the natal chart reveals all the other things that work together to influence variations of the sun/moon signs. *eyeroll*
Some capricorn traits are accurate for me - pessimistic, ambitious, serious, strong willed, stubborn, desire for knowledge, etc. Those are capricorn traits. Also, I've been told that I'm "too logical", a bit of a know it all, and that this is another typical trait of capricorns.
I have a lot of traits that are very antithetical of the capricorn way - I'm very talkative, loud, expressive, warm and friendly (generally), I'm not reserved in most situations, I'm really funny and I have a positive side to counter my pessimistic nature, I'm definitely not into most traditional, conservative ways of being or thinking, I was never quiet and obedient, almost always question and challenge authority figures, I don't have a very cautious nature when it comes to exposing myself - I'm extremely open and honest, wear my heart on my sleeve type of person, etc.
