@Haejin you have made yourself a focus of attention, with all of your best intentions, to help. I read in the comments of your blogs, so many people, including myself, who fully appreciate your knowledge, sincerity and drive to help others master your method. In my experience your generosity in what you give is truly amazing.

If it’s any consolation, I’ve learned more from you in the last two weeks than I have in the past twenty years!
