Look at all of the following:
What sign is the Midheaven (MC) in. Start with the keywords describing this sign to give you a general idea.
Next, look at the 10th House, which is the house of career. What planets are in it?
They deeply influence the social destiny of the native. Analyze from the planets' keywords. And what areas they rule. This will tell you the likely areas in which you will practice.
If there is no planet in the 10th house, look at the ruler of the 10th house, namely Saturn. In what sign is Saturn located? This can tell you what kind of field you will be working in.
You should also look at the planets that are in aspect to the MC and the fixed stars (in conjunction or in opposition with the MC with an orb of 2 degrees maximum)
Then the 11th house shows among other things how we can earn money. The sign where the cusp of the 11th house is located will inform you about the field (you have to look at the fields ruled by the sign).
Then, if you are still young, you should look at Mercury as a factor of communication and learning abilities. It will be especially important to identify the potential and the difficulties. Which sign is Mercury in? Does it suffer from bad aspects? Aspect with fixed Stars ? Etc
Then, in the same state of mind, look at the House 3 - House 9 axis which is the axis of studies, intellect, reflection, communication, social integration. It is necessary to look in which signs. Are the cusps of the 3rd House and the 9th House. See the keywords related to these signs.
Then you have to look at the rulers of the signs of the 3rd House and 9th House. For example, if the 3rd House has its cusp on Cancer, look at which sign the Moon is in, as well as the aspects with the other planets.
Next, look at the 6th House, which represents daily life and constraints. It gives an idea of the framework in which we may have to evolve every day, vocation or not. In which sign is the cusp of the 6th house? See the keywords attached to the sign. Are there any planets in this 6th house? Look at the keywords of these planets.
I also look at the Lunar Nodes, the South Node can indicate where you had skills in the past, the North Node shows where it would be wise to go. That can give you some indication.
I look at the Part/ Lot of Fortune. What sign, what house it's in. If there are conjunctions, the other aspects.
Finally it can be useful to look at the 7th house (and cusp of the Descendant), which is certainly the house of the marriage partner but is also the house of the partners (commercial contracts, etc.). Which sign, which planet in it, ? etc.
I have been learning Astrology for several months, but I am not a specialist, if I am wrong, advanced members will correct me. I'm just giving some guidelines!
Good luck!
