Beginner here: Is my current idea about the planets in their own sign accurate? More info in body
I will give an example, let's say Mars in Aries in the third house, he is Strong in Aries, but he is Mars so could this manifest as competition and conflict with siblings? Sharp way of communication etc.
My reasoning being that Mars is a planet of aggression etc. So in Aries he would be "free" to be himself fully. He won't not do Mars things.
I apply this reasoning to all planets. Is it accurate?
