My dear students,
I have just finished grading and my students get a range of grades from As - Fs.
May I teach you one last lesson? For those of you who did well in this semester, keep on working hard. There are no "bests" but "betters". For those of you who did not do well, don't get upset. This is not the end of the world. I have been through so much that I can tell you this. There will always be something worse than worst. You just have to let "yesterday" go, do your best "today", and don't be afraid of "tomorrow".
Our class has come to an end. It has been a pleasure to teach you during this summer. I am very proud of you guys.
