“Ask yourself is it right or wrong and act accordingly.”

This quote implies that you need to make sure you are always doing the right thing. Like keeping promises. And also behaving and listening to your parents. For example following your curfew and rules that are implied to you when you are told. You need to always think about what you want to do and what you are doing you can't just go around taking dumb decisions. You need to remind yourself and keep yourself out of trouble. You need to be able to be trusted upon. And for that you need to be a person who chooses the right 24/7.
