Pisces Neptune Mutable Water Negative

What you'll like about each other:  Affectionate, sensitive, caring, fully in touch with emotions, flexibility, emotionally involved with life.

What will drive you crazy:  Too laid back, procrastination, overly emotional about practical issues, inability to deal with hard realities of life, making excuses for self and others.

Unless one of these Fish has some fairly strong Earth or possibly Cardinal elements, this couple may do a lot of floating through life.  They will both be quite happy in their undersea world, but will have significant difficulty attaining any significant goals, staying within a budget and maintaining relationships, perhaps even keeping a steady job.  Pisces are very immersed in their emotions and just about everything they do will be motivated by them.  If they feel they want to do something they probably will, if they feel they want to go somewhere they probably will, if they feel they want to buy something, they probably will and then a day or two later not remember why they wanted it so badly. 

Bear in mind that their ruling planet, Neptune, is not exactly the logic champion of the universe.  While we all need some Neptune in our lives to keep in touch with our fantasies and dreams to say nothing of imagination, if afflicted it can make us delusional or keep us from seeing the way things really are.   It's easy for Pisceans to get lost in a world of fantasy.  This is not necessarily a bad thing as long as they keep at least one foot in the real world.  I saw a plaque once that explained it fairly well.  It said, "I live in my own little world but they know me here."  But obviously it's usually a good idea to hold a steady job, pay your bills and do all those things responsible adults are expected to do.  Now I'm just waiting for some Pisces to ask me why.  I suppose my main answer to that is people should be self-sufficient, at least as far as they're able, and not depend on others to take care of them (my Capricorn sun/Virgo ascendant is showing, I know).  That brings to mind the bumper sticker that says, "I work because thousands on government assistance depend on me." 

Okay, okay, so who's really smarter?  In a somewhat lame attempt to remain politically correct I won't ever go there.  I've know numerous Pisces in my lifetime and am currently living there myself as a move-in via my progressed chart, and in all fairness most of them were hardworking and self-supporting.  I know one that is probably the most dedicated, responsible person I know, but she also has a Grand Earth Trine which explains it.  So I'm not trying to dis the poor fish out there by any means.  However, I guess I'm trying to warn everyone else that if you get two of them together, they're probably going to be living in The Magic Kingdom.  The question is whether or not you care to join them.
