Understand your family well. If you don't then there can be many misunderstandings and fights. Be with them whenever you can and get to know them better. A lot of families now don't get to know each other too well because they're too busy.
Plan some family time, like, a movie, or eating dinner together
No one wants to be ignored just for some meeting or work. Give time to each and every one of them so you can understand every individual properly and this can prevent any misunderstandings in the future.
