When you have no idea , what's when and how it went wrong...

How can people stick with one bad thing when there are many good things that they did for you ! It's really fascinating how I noticed other when I'm doing the same. But what really amazed me is that I can't help it to stop nor fight with my inner feelings. And I don't know whether I can notice in further steps of my life, even just a little. Or, will be I be completely covered with my dark and burning ego just like I used to do?
