I never said a child should get all A's in school. A lot of great people didn't necessarily have all A's, but most of them did stay in school and got the most out of their education. I have been watching Breaking Amish and realize with their 8th grade educations they have a hard time making it outside of their community. We had a community garage sale a week ago. We have a fairly large Amish community in our area. Some of the them could not even count out their money (and this was on items adding up to around $5). I see people in other countries who are deprived from having educations only to be brain washed by their leaders. An education is the only way we as a nation and as people can go forward.
I do want to say hand in hand with this you need to support your child with love, confidence, and self esteem.
