Trust is my most valuable treasure. Recently, I am in depression, but I still got a lot of help from my friends around me and in Italki, I said to myself that I have to be brave enough to insist on what I want to do, and then I will be happy and feel inner peace. I just remembered a similar experience on 2nd Mar., 2009, I called National Book Fair Organizing Committee with fear and trembling, after recommending for four times, I reached Mr. Tian. I told him I wanted to built a rural library for children in village with the help of the public and government; I was willing to be in responsible for the whole process. On the phone that time, he said: "We can talk face to face when convenient." I appeared in his office at once after finishing the conversation; he could feel my sincerity. After times of hard talking, Mr. Tian agreed to cooperate with us, In that year, I worked hard with my friends, from a team with only 2 persons to a work team with 40 persons leaded by me, I thought easily and simply, as a college student, I need to do something to the society; as a Chinese citizen, I have responsibilities to make more people know about vulnerable groups. After the party, Mr. Tian said: "You are the first college that builds the rural library in Shandong Province. Your enthusiasm makes me trust you absolutely." At that time,I found the huge power of passion and how to get trusted from others. Trust is my most valuable treasure.
