I tend to agree with you there. I don't use the outer planets. I used to, because when I learned astrology the modern psychological stuff was all that was on offer. And that went on for a good twenty years (ouch). But the more I worked with them, the more convinced I became that they didn't show anything, or at least they didn't do anything but confirm something you could see elsewhere in the chart. Ironically, I tried one of those Pullen charts at astro.com, and by that, Pluto is my dominant planet. By a mile. Bwahahaha.
Here's what I'd do if I were you. Find your chart almuten. That may well be your heart's desire, and quite possibly your guardian angel as well - if it comes from that planet (sort this out from wishful thinking!) it's not going to lead you wrong.
Look at any planets on the ascendant. They are going to have a profound effect on how your life plays out.
And because everything isn't active at the same time to the same intensity, look at the lord of the year during each solar return - I give more weight to the rising sign of the solar return than the profectional lord, but both can be important. NB: If it happens to be Saturn, and Saturn and Mercury are conjunct in your natal chart, and that's Saturn's closest aspect, then Saturn and Mercury are both going to be highly active in your chart. Always look at the planet that's in closest aspect to the LoY, chances are EXCELLENT that you'll get both of them. Or in my case, more than that, because I've got a ring of sextiles that are all within a degree. Ghaa.
It can take a while to get the patterns down, and the only way to do it is to really study what the planets mean. Then you'll start to get the clicks, see where it's playing out in your life.
I wish I could hand you a simple answer, but honestly, that doesn't work too well, because life - it's not all that simple.
