[填空题]We all hope that the values that are important to each of us are passed along to our children.
Often, however, that hope is challenged by a flood of pop culture messages, peer pressure, and over-scheduled lives that leave little time for good counsel or reflection. It’s easy to forget that learning values and character at home is as important as any schoolwork or extracurricular activity.

While grade school, high school, and college can teach skills and proficiency, it’s up to parents to teach children the attributes that make for success in the real world--diligence, a cooperative attitude, creativity, optimism, assertiveness, and honesty. Schools--particularly college--don’t focus on these issues. That’s the job of the parents, so take the assignment seriously. Send your kids into the world ready to handle not only the tasks of life but also its
