Moon in 4th house.

So, lets see what Moon can do in 4th house without any conjunction or aspect from any other planet. 1st lets see what these 2 things represent -

Moon represents Mind, Emotions, Mother, Local Government, Peace of Mind, Home Environment, Water, Milk etc.

4th house represents your home, home environment, homeland, mother, nourishment, childhood friends, peace of mind, conveniences etc.

So, when Moon comes into 4th house, these people really get emotionally attached with their Mother, because 4th house and Moon both represent Mother, so it becomes double energy representing Mother. Mother's teaching and nourishment means everything for them. 

These people are highly emotional and emotions can be imbalanced. They are very motherly in nature and love taking care of others, so best profession for them becomes Nurse, Teachers where they are required to take care of people directly.

Their Mother is most probably someone, who herself loved helping others .

Overall, a great position for Moon to be if anyone wants to take care of others.
