Is this compatibility possible? Fire and Earth – two different elements that never seem to mix. However, with the right maturity level this is definitely a possibility!
Capricorn takes the world very seriously, and brings a special pragmatism to the relationship that you tend to lack. You, on the other hand, will have a challenge (Oh boy, challenges!) in teaching your Capricorn the value of being optimistic rather than a realist. Capricorn, being an Earth sign, is very stubborn and set in his ways, so this may take awhile.
But oh, it is worth it in the end if you can convince your Capricorn to change. Capricorns, once trust is earned, let their love flow easily and often, and you will often feel appreciated and admired.
Your Capricorn, once out of their shell, has one of the most amazing senses of humor. You will always feel entertained and taken care of when with your partner.
You can, in return, offer your partner much as well. Sagittarius is an explorer, always on the move and adventuring into every nook and cranny he finds. Capricorn, while not the most willing of explorers, will be amazed and happy once you can finally drag her out with you on a venture.
While the Goat can be as stubborn as can be, your special Fire may be enough to melt down his defenses and give him the ride of his life.
