I(2nd row, most left) was a part of my church's Youth Zone (YZ for short) where we have youths aged 12-18 gather for worship sessions, annual camps and various events.
As an older YZer, I usually serve as part of the camp committee where I help lead the Publicity and Programmes committees as I have experience working with videos/graphics and I am able to work well with people. I also spearheaded a writing initiative within the youth community (see below).
