What you can charge for
The second house covers the skills you can keep doing, get better at, and exchange for money. Not what you are best at in theory. What you can sustain.
People often discover their real second-house skill is the thing they find easy and assume is worthless because of it.
What you are known for
The tenth house covers your work in public. Your direction, your reputation, and the standard people come to expect from you.
It is the part of the chart that cares what your work looks like from the outside, which is uncomfortable and also how most opportunities arrive.
Where the two meet
Every house is run by a planet, and that planet usually sits somewhere else in the chart. The planets running your second and tenth houses point at other areas of life.
Those areas are often where your earning keeps colliding with something else. Home, partnership, health, travel. It explains the pattern people describe as always the same problem in a different job.
The limit
A chart cannot name a salary, an industry, or a job title. Anyone telling you otherwise is guessing.
What it can show is how you negotiate, how you cope with being visible, and where you keep undercharging. Those three account for a great deal of the difference between two people doing the same work.
