Setbacks become part of the learning experience. Through such experiences, a child learns personal limitations and how to maximize personal strengths. Parents need to teach personal values over conformity. Students need to do what's right before they do something because everyone else is. The peer pressure on middle and high school students is incredibly high.
Parents are very important to developing character in their children.
Parents can create clear boundaries for work. School is a job and should be viewed that way. It still can be enjoyable, however, just as many adults enjoy the work that they do everyday. When children need to work, they should work without the TV, radio, etc. When they play, they should free themselves completely from work.
