I dug the cards in your above spread out of my deck and recreated it.
Some themes I have noticed.
The Five of Disks, does indicate worry, but is also indicative of Mercuary in Taurus. Going with what you where saying, this is probably signifying that is has taken you a long time to reach a decision, as well as you've been concerned that those decisions may upset the stability you already have.
Art, is a card of blending, but also of communication - this is shown as Art's symbol is that of Saggertarius, a sign which deals with communication and seeing the larger picture - so to speak. Thus, it could be you've been worried, but have finally decided on a course of action because you are now aware how it fits into the larger picture as a whole and can now persue that aspect.
The Universe and The Chariot are how to resolve your issues. So I am looking at these cards two ways - You want to be successful (Universe) but to do that you need the Drive (Chariot). I am pretty sure this is the angle you looked at. The other angle, is both cards combined is Saturn in Cancer. This could indicate a need for responsable decisions in reguards to your domestic situation, or a unlaying issue that you require a safe, secure home situation, rather then being at odds with yourself and someone else.
The Final Outcome is Adjustment, which is also the Sign of Libra. Things will balance out at some point. Libra rules relationships and is a soical sign. I think Adjusment in this case however, is showing that there needs to be adjusment made to balance the scales in that relationship.
It is worth noting, that since this was on Science, the Six of Swords (which also shows Mercuary in Aquarius) the entire spread except for cards 3 and 4 indicate communication on some level. The diferance is, you may have gone from the 5 of Disks, and picked a path for yourself, and now your stuck in the Six of Swords, which - being Swords (indicating Logical Thought) and Aquarious (a fixed sign), may mean since the swords are pointed inward - over-thinking the matter.
Clearly however, communication is key, and since to communicate something requires some one recieve that comminucation, automatically indicates another person, or persons. So while you have thought and worried about this and tried to see the larger picture - only by taking control (Chairot) and Responsability (Universe) will you see any impact (Adjustment) from all the worry, planning and thoughts you've had on this topic.
------
As to your orignal reading in the first post. Adjustment could indicate the need to balance the thinking side of yourself with the Action side (Mercuary in Aquarius with Sun in Aries). All thinking makes you unable to move. All action indicates undirected thoughts. Only by having a balanced perspective can one obtain Balance (IE - you need to balance your scales, which will take Adjustment).
