The answer is very simple, accept, repent and rebuild.
Accept who you are, repent what you have done, rebuild a new self.
However, this is very hard to do, because it conflicts with your current self.
Thus, the alternative methods are:
- Eat simple food – sacrifice your food desire.
- Do charity – sacrifice your time, ego and comfort.
- Live a simple life - do away desires.
By doing these things, you train yourself to let go your wants.
