A spreadsheet with rows you actually understand, and a number underlined twice in pencil so you do not forget what it cost. Your mind goes straight to the material here: pricing, contracts, the patient arithmetic that turns a loose idea into something that pays the rent. That is Mercury working through your second house, the house of what the body owns and counts as worth keeping. You enjoy the math other people call tedious, and you should. Your own voice is part of the inventory too, an asset you tend rather than spend. Treat a negotiation as a craft and not a brawl. Say what a thing is worth out loud, in small clear figures, and watch how that steadies the whole conversation. Watch the day you mistake the spreadsheet for the security itself and start recounting the same column when the worry has nothing to do with money. Honest bookkeeping is its own quiet dignity. A budget you actually keep does more for your nerves than any pep talk, and the numbers tend to come back kind when you have been paying real attention to them.
