When someone stumbles upon a Capricorn, they may notice a hardworking, go-getter who they grow to respect. Capricorn's respect is garnered from them being both dependable and reliable. All Capricorns need is a goal and a blueprint; the drive to achieve is innate. You may notice that this Capricorn is nitpicky in the way they want things done. You might catch them spending endless hours consuming how-to tutorials on Youtube, consuming information like a perfectionist would painting a masterpiece.
Capricorns are earth signs, and by now, you know the earth is related to being grounded, disciplined, and practical. Capricorn is also a cardinal sign which speaks their quick initiative and always seeking the next thing. Their symbol is of a half-goat half fish. The tail represents the exploration of spirituality and things below the surface, while the top half (goat) represents their groundedness and matters of physicality.
Capricorns and water signs (pieces, Scorpio, cancer) are an excellent mix for many reasons that I won't spend the time writing about. However, the main reason lies in the water sign's deep connection with emotions and intuition. Capricorns can lose themselves in their work and grow apathetic towards those they care about.
So to get back to the question, a Capricorn screams of discipline hard work, responsibility, and persistence. Though each individual Capricorn hast heir kinks to work out, traces of these traits can be found in any with a strong Capricorn influence in their chart.
This is a good time to mention that you could gain more insight into the psychological factors surrounding an individual by exploring other planets along with the sun sign by using a Natal chart. I hope you found my answer beneficial and good luck.
