I think the single biggest lesson of my thirties has been "usually if something seems like an obviously super broken thing that no one is fixing, it actually is really hard to fix. but it's still worth trying anyway."
Seriously. Understand what's going on. Take stock of the actual barriers between you and your actual goals, not the automatic more measurable proxies for those goals we make up in our heads.
(For example, if our actual goal is "more children in loving households with at least two adults looking out for them and caring for them, fewer children living in homes where they are neglected or deprived," we sometimes talk about measuring "children in two-parent households."
But that's not the actual goal: it's the proxy we're using to approximate the actual goal in any given moment, because you can't directly measure real net child social support in the moment very effectively. We need to use proxy measures to help us find out how complex phenomena are linked, but it is crucial to remember that they are tools and not blueprints.)
And if something seems so simply broken and easy to fix "over there," consider that probably there is a snarl in the knot that you can't see, hiding part of the so-simple problem from view.
