Alot of the same element?

Generally yes, they are the three most important. And you aren't alone with having three fire signs with Sun, Moon, and Ascendant. With you Sag sun you are probably quite open and enjoy the outdoors and anything that requires exploration. Travel too. Higher education is important also for Sag. Your Aries moon probably makes you a little hot-headed at times. Aries is ruled by mars and it really isn't one of the easiest moon sign placements as the moon is home, family, emotions and Aries is all action, a warrior, and enjoys a good battle. Your Sag ascendant also gives you an outgoing personality and probably alot of fun to be around. Just watch that Aries moon and learn what battles are worth fighting for and what battles are not worthy of a battle. This is important. You must learn to choose wisely or your emotions will always be in high gear just looking for someone to give you a hard time. Save your energy for battles worth fighting for as a cause, a cure, a charity. All worthy of your energy. You probably have good energy as fire signs enrich ones energy. You don't mention where your Scorpio lies so try to include that next time as Scorpio is a powerful sign, Hope this is helpful. Good luck and bless you.
