What Does it Mean to Have a Saturn/Neptune Midpoint Conjunct My Capricorn Ascendant?

A midpoint as I understand it is like a bridge between the two objects in question, so to venture a guess i'd say it probably means something like how you present yourself is the key to making your saturn and neptune work together harmoniously - dreams-into-reality kind of thing. But I'm not sure, so I'm interested in seeing what other answers you get:)

In my opinion it's pretty much as you say, for what that's worth. You're very aware of what goes on around you, or in the world you live and if necessary you have a good, practical way to use your imagination when and where necessary; you're probably a good problem solver. Childhood experiences has probably given you a cautious attitude and a lot of common sense. You'll probably achieve what you want, or be well on the way, later in life.
