Leo Sun in 1st house, Cancer Jupiter in 1st house?

To my understanding, Jupiter in the first house people will govern traits that of a Sagitarius rising? So being a Leo sun how does Jupiter in my 1st house affect my personality, Jupiter is in cancer! I know awesome stuff. I have aries moon, so is my personality more like someone with Leo sun, Aries moon and Sagittarius rising? My problem is that I run straight into situations without thinking twice about it, then in the end ditching a goal or whatever onto something new, would the solution be to find something that will NOT make me want to try something new? What's something that a second decan sagittarius rising person would LOVE to consistently do, I am going for an acting course for a serious career in acting. I feel that self-expression is fun! Please do not dismiss my question as if you were a true astrologist you would understand that my need for such a distinctive answer is influenced by my need for awareness of myself as self-introspection has been quite appealing to me this year. Please, answer. I would. Self-discovery is a looonnnngggg search!
