Good question! It's like this: a reading is set for a period of time, and not everything in your life is going to be of equal importance during that time. You could be really focussed on your career, but in your home life - nothing exceptional is going to happen, it'll just be day-to-day routine for the most part. Say that your significator is over on the right with Fishes (money), Moon (honours or recognition that usually comes from career these days), Anchor (stability, also relates to career), and over there way on the left is the House. Career will have a lot happening, your household - not so much.
Or maybe the Tree is far away from you - health is not a big concern, as it would be when it is close.
You can still glean something from reading the cards around the House or the Tree, sure - but whatever it is, it's not going to affect you as much as the job stuff does during this period, and people's lives don't usually have a lot of important events in all areas at all times. Which is good, because the stress would just be too much.
Does that help?
Absolutely that helps! Thank you!!
