There’s this quote attributed to Rabbi Yisrael Salanter:

When I was a young man, I wanted to change the world. I found it was difficult to change the world, so I tried to change my nation. When I found I couldn’t change the nation, I began to focus on my town. I couldn’t change the town and as an older man, I tried to change my family.

Now, as an old man, I realize the only thing I can change is myself, and suddenly I realize that if long ago I had changed myself, I could have made an impact on my family. My family and I could have made an impact on our town. Their impact could have changed the nation and I could indeed have changed the world.

There are two lessons here. First - the best way to affect meaningful change is to start local. Rather than spending a lot of time agonizing over national politics, get involved in your community - your neighborhood, your town, your apartment building, even just the house you share with your family. Your community will take better care of you and the other people that you care about than any national government ever will.

Second - ultimately the only person whose behavior you can change is your own. Don’t be too harsh with other people when they don’t behave the way that you believe they should. Be a more stringent judge of your own behavior.

But temper that with this:

Whatever you do, don’t congratulate yourself too much. Or berate yourself too much either.

Your choices are half chance. So are everybody else’s.
