Your career and purpose in life can be seen by 2 things such as :

1) The sign of your MC
2) The house and sign placement of your NothNode

The 10th house represents your career and reputation. It goes hand in hand with your second house, which represents your own money and income, aswell as your attitude towards making your own money. When the ruler of the 2nd house makes a harmonic aspect to the MC or the 10th house ruler, it simply means that you will be able to make good money for yourself. Especially when Jupiter makes a good aspect to the MC or is in the 10th house, it can indicate a good career-life. Bad aspects from Saturn can indicate a career late in life.
The hard aspects that are made to the MC and it’s ruler indicate obstacles along the way your path to a career. The point or planets that make these aspects represent of what nature the obstacles will be.
For example : If the ASC ruler is square to the MC = You will be your own obstacle. If it’s the ruler of your 6th it indicates your health being an obstacle.

Northnode is your soul purpose and karmic destiny. It is the astrological point that breaks laws inoder to achieve it’s goal. The sign and house placement of the Northnode represent the direction you should go in life. When it’s placed in the 6th or 10th house, it will have benefit on your career, when it’s placed in other houses, the impact is not so big on your career life.

• The house and sign placement of Saturn and Chiron
• The 2nd house ruler and occupying planets

The house and sign in which your Saturn in placed, show where you doubt yourself and the area where you are challenged. It shows what you need to learn and work on. And sometimes you end up using that in the professional field.
For example : if someone has Saturn in 6th in Cancer, it can indicate someone who struggled with health and weight, and want to become a coach for people with eating disorders or diabetics. Chiron acts in the same way. Chiron is the wounded healer, the house and sign it is placed in, show in what area of life you have a painpoint. When you overcome that pain and heal from it, it can trigger some individuals to use their knowledge about this painpoint to help others.

The second house shows your attitude towards money and work, it represents your work ethics. As mentioned before, it goes hand in hand with the 10th house. The planets occupying the 2nd house can show in what nature the individual prefers to make money.
For example : when Mars is in 2nd, it shows an individual who is determined to work hard for the money he earns.
When there are no planets in the 2nd, you have to look at the sign on the cusp of the 2nd house and see where it’s ruler is placed within the chart. Also check what aspects are made to that ruler to see the challenges and the benefits.
For example : if the sign on the cusp of 2nd house is taurus, than Venus is the ruler. If Venus is placed in the 7th house, it can indicate an individual who prefers to have a good work-life balance in their career. Aswell the individual can have financial benefits from the partner when good aspects are made from Jupiter or the 7th house ruler.
