I wish you luck. You do need to grasp that an advisor is not, or not only, a teacher. He or she needs to understand and relate to a teens world. If that teen is a yeshiva high school kid, as in some NCSY regions, it might be easier to relate. If that teen is a public school kid with no affiliation and little or no Jewish knowledge, as in other NCSY regions, it might be harder.
There’s also age to consider. I don’t know how old you are; and there are some advisors (I’m thinking in particular of one very dedicated woman in Minneapolis)who are older (she is in her 50’s) but its uncommon, and 20-30 is the norm. There are also chavrusa and other learning opportunities with NCSY kids where age and relatability are less material to the kiruv relationship.
