1) Dave was sad when he did not make the school basketball team but his mother told him he can do better and to try again tomorrow. 2) The next day, Dave was upset when he got low grades on a math quiz but his mother reminded him of the same advice. 3) Dave continued to practice basketball and study harder for math, and by the end of the year he had joined the basketball team and was awarded best in math, showing the benefits of positive thinking and not giving up.
