Things change one step at a time

I think that the only way we can do a positive change in the world is little by little, setting small goals that are realistic. For example, many people try to change the way companies or goverments make their rules, or how they rule in the case of goverments. But I think that no matter how many protest people do, the changes they achieve with this are at the very least insufficient.
I think that one way to make a better world is acting with honesty and responsability; this is perhaps the most efficient way to solve society's problems. I mean, what good could be to protest against some industry polluting a river (don't get me wrong, I care about the planet just like anyone else) if you can't even get along with your family?
What I'm trying to say with this is that there are priorities, you can't try to change the world if you can't even manage to have a decent social life, so first things first.
You can say that the problems that you're trying to fix are more important because they affect society or enviroment in terrible ways, and that might be true, but how people intend to fix that if their whole life is a mess? Fix your life first and then you can move on to bigger problems.
Because if your life isn't in order, you can't expect to put order on bigger things.
