How to repent of your sins

If you know you are wrong, don't do it again. Then it's best to warn others about the impact this will have on you. If it is good, give it back to the right person. If you can't do anything else, just make some compensation to society and others. If you are injured or affected in other ways, you'd better accept it calmly. I believe that as long as we really change and do, God will forgive us children who have made mistakes.
