No trinity is a lot harder or better or worse than the other. Everyone has to work with what they have. Being a Capricorn Sun, you are serious and responsible. You are a planner and normally have goals in mind or at least some game plan for the future. You are the type who starts planning your summer vacation right after New Year's. The Moon and Rising sign are both in fixed signs, so you are stubborn, or at least persistent, and like to get your own way.
Leo Rising means you give off a sunny, friendly vibration, so people are drawn to you. You seem strong and independent, and can be a tad bossy. But people like you and you like to surround yourself with ones you like. The Aquarius Moon is about your emotional makeup. You have a rebellious streak and may be drawn to relationships or situations that are "different' or more stimulating than most Capricorns would normally like. Leo people are very romantic and usually stay in one relationship, but Aquarius ones are hard to pin down and like variety. So depending on where in your chart the Moon falls, you have that dynamic of wanting to find a partner, yet not really wanting to commit. That's the only challenge I see here.
