live by something

I'm going to live by myself and have a good time.

The problem is how to learn to live by them.

She lives by herself and does not see many people.

Let me live in my house by the side of the road And be a friend to man.

But what we live by can't actually be put in words.

Lived in only by people below the age of 18.

I've always lived my life by the law of the land.

For a year now, we have lived by window light.

As free people, we should live by a higher standard.

Perhaps there has never been a time when people needed words to live by more than they do now.
