Absolutely. I really, really like this approach, because that's exactly what a number of NGO's, charities and local communities focus on doing (at least where I live - in the UK).
It's one thing to wait for the next elections, hoping something will (maybe) change for the better, but it's another thing to engage yourself in the life of your local community or region and try to contribute to fixing things on a smaller level. And sometimes those small actions grow in significance and are a prelude to a real change.
We've had a number of "small wins" in the UK lately when it comes to women's rights, and all have been done as a result of activism rather than politics. So as long as a I can see the small change happening, I think it's good to encourage everyone, even the most jaded of us, to step out of their bubble and help out - even if just a little bit.
