For me its mostly societal things.

Eg: I have to shower once every 1/2 days
I have to wash the kitchen every 1/2 days
i have to wash my clothes once a week
I have to keep my anger inside because it is socially unacceptable to express it
I have to wear black to funerals
I have to say X, Y and Z to people in certain situations
I have to NOT say a,b,c to people in certain situations

Its like a huge policies and procedures manual to life
