"All blame is a waste of time. No matter how much fault you find with another, and regardless of how much you blame him, it will not change you. The only thing blame does is to keep the focus off you when you are looking for external reasons to explain your unhappiness or frustration. You may succeed in making another feel guilty about something by blaming him, but you won't succeed in changing whatever it is about you that is making you unhappy."
I was just talking to a friend who was telling me the mistakes that her daughter was making in her life and the fact that she was likely to blame? I know that it is easy to accept the blame because you are the parent, but there has to be a time when you step back and let them learn from their own mistakes.
I think that making mistakes just might be a learning curve that a young adult has to go through. Make the said mistake and then learn from it. I know that I made my own fair share and I had to accept responsibility and I certainly didn't do it again... or blame my parents!!
