No one to blame but myself

I have often heard parents blame teachers for a child's academic difficulties. I have also heard teachers blame parents for a student's lack of progress. But, as both parent and teacher, I have no one to blame but myself when things go awry in the school room, which they did a bit this week. When that happens, I don't have the luxury of trying to pin the blame on someone else. I simply must figure out where things went wrong, retrace a few academic steps and then move forward in a way that, hopefully, best helps my students/children reach their full potential.
