On 22 January 2010, Dr. Yang Saing Koma, president of CEDAC will organize a series training for CEDAC’s staff. At that time, the training will focus on Learning is Sharing and Sharing is Learning. I myself, Yim Sok Sophors, is going to present the book, called “30 minutes before a meeting”. Hopefully, I will be able to learn from myself and to learn from the other.
