Mom says I have no conscience. How can I change it?

You are spoiled by your parents. Maybe you will feel wronged and depressed, but you are really spoiled.

If you want to change, you can live independently for a period of time, in the dormitory or in any unit. In short, your parents are a regular source of income, but not much. If you want to spend more money, you can earn it yourself.

If you have the courage to do this (but the jobs I mentioned don't include hanging out with gangsters, being gangsters or being brothers with gangsters, and children your age are easy and willing to treat those people as heroes), you will be completely changed in two months.
