When he was in high school, Tep Livina was just another gangster who did not care much about learning but playing around aimlessly. Yet, when he entered the Institute of Foreign Languages (IFL) in 2006 as a college student, he gradually changed his life and become one of the best students IFL has ever produced. In 2009, he honorably graduated as a valedictorian and was chosen to deliver the graduation speech to over 1000 graduates and distinguished guests present during the graduation ceremony. Nowadays, a master candidate in TESOL, he is running an educational company​ called EdNICHE offering many services including helping the students to learn English language more effectively and become outstanding students in their school.

In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDxevents are self-organized.* (*Subject to certain rules and regulations)
