I think you misunderstood the "help other people" with "do volunteer work". The two things are not necessarily related. Nobody is going to befriend you just because you help children with troubled families, but surely they will be more likely to befriend you if you help them with their everyday life, like helping them moving out of an apartment, giving them a shoulder to cry on when time is rough, buying them a beer after a bad night, helping them fix their bike, etc etc.

It's not about helping everyone, it's about helping the people you care about (supposedly, your friends)
