I think the difficulty with this concept is trying to guide your kids so they won’t have regrets for mistakes they could have easily corrected. One daughter has a 3.8 GPA UW in her junior year. A tad more studying and effort (turning in all her homework) her freshman year and those two high B’s could have been As. Now as a junior, she realizes she can’t be one of the 30 valdictorians at her high school.
I hope learning the lesson in high school will be better than learning it in college.
