Dear Student (3)

You said you are incredibly thankful and lucky to have known me, but it is really I who should be thankful and honored to have worked with you. As a tutor, all I do is to bring the best out of my students; and the very best you are. You deserve everything you got. Students like you make this soul-sucking and thankless job worthwhile for me. Never stop being curious, earnest, and compassionate. And when you can, please pass down the torch and make the world a little better place.
