How to start over after a life of sins?

People are difficult sometimes. Right? If you had an argument with someone, and then you try to talk to them again, you’ll feel like things are not the same anymore. They might not meet you with the same open arms and complete acceptance like before. And if you had several problems or downfalls with the same person, then that person might black-list you and make sure not to accept you back in his/her life because of your mistakes. Remember this hadith?

Anas (May Allah be pleased with him) reported:

Messenger of Allah (ﷺ) said, “Allah, the Exalted, has said: ‘O son of Adam, I forgive you as long as you pray to Me and hope for My forgiveness, whatever sins you have committed. O son of ‘Adam, I do not care if your sins reach the height of the heaven, then you ask for my forgiveness, I would forgive you. O son of ‘Adam, if you come to Me with an earth load of sins, and meet Me associating nothing to Me, I would match it with an earthload of forgiveness.”‘ [At- Tirmidhi]
