What is the best advice your father ever gave you?

One day I had a fight with my Mom and shouted on her and didn�t had my lunch. I went out with my friends and had food. Later when I came back, I was hesitant to face my Mom so I went to my room and started watching TV.
Then my Dad came to me and asked why you didn’t had lunch today?
I said I had food with friends and don’t want to have food cooked by Mom as I had fought with her today.
He listened to what I said and started speaking. You know, I sometimes don’t like what your Mom says or what she does but have you seen me shouting at her or fighting with her.
I said No
He said, if you or me or your sister fight with your Mom then we can go out with our friends or colleagues and have food, chill out and come back whenever we want but have you ever thought of your Mom after you shout at her. She will sit there and think for the whole day why you shouted at her and she will not have food for the whole day. So think before you shout at her or fight with her, you have a whole world outside waiting to hangout with you but for her you, me and your sister is the world and when anyone of us shout at her then her whole world comes down. For you it’s
just a matter of few seconds anger so if you can suppress it for sometime you can make her world happy.
I honestly try not to shout or fight with my Mom anytime after that or even if I fight with her I make sure I apologise as quickly as possible.
Let’s make our Mom’s world happy always….
