If you're just starting, you might want to pick up a For Dummies or For Idiots. I've read them both and they aren't bad. Either one will give you an idea of planets, signs, houses, aspects. Learn it, but don't get married to everything it says.
There are so many types of astrology today that you will at some point decide what you want to go into, but it's good to get a very basic idea of things first.
Maybe you'll like psychological, or western trad, or jyotish, or cosmobiology will tickle your fancy, or maybe horary seems more interesting than birth charts. I encourage anyone to go into horary first because it's the easiest and most practical form of astrology, and it will really show what the planets do. Then graduate to natal, or just stick with horary if you like. But a lot of people don't fancy horary, so...
Do your chart, but do the charts of people close to you, too, or any historical figures you like who have a well-documented birth time and life events. Some people get so obsessed with their own charts that they start to gloss over anything else - and that's going to give patchy learning at best.
I was just wondering how you each chose to structure studies. Did you start with a particular house system, genre. Or did you try and get an all encompassing method of study? I want to know a lot, as I have lots of areas of interest but I also want to do it the right way.
