Encouraging students to cultivate good habits is not only the building blocks for their lifelong achievement, but also a best present for them. Based on this philosophy, this study investigated the students with the method of “charge structure” in the realm of habitual domains founded by Professor Yu. This study selected the approaches of: “three kinds of emotion” and “healthy circuit patterns: smile, deep breath, and standing up straight” and requested the surveyed students to continuously keep the “diary for changing habits” for twenty one days. It was expected that by keeping a diary, the circuit patterns could be reinforced by the charge structure and, through this process, the students could learn to smile, deeply breathe and stand up straight which all facilitate to escalate their energy and help them to learn and live happily, healthily and confidently. This study assumed that, by the mechanisms of “four steps of charge structure” in habitual domains, students can increasingly strengthen their good habits such as smiling, deep breathing and standing up straight, etc., and quit the harmful habits. The retrospection through the replication of twenty-one-days diary keeping not only facilitates students to cultivate their good habits but also to understand the ways to change their behavioral habits. Hence, it will be their lifelong concomitant present learned from school. The empirical result showed that students could cultivate their good habits and quit their harmful habits through the “diary that changes their own habits.” Moreover, parts of these investigated students even felt surprised by the consequences and hoped to consecutively keep the diary to change their malignant habits.
