What is the LBJ quote about knowing what is right?

Something like “You know, doing what is right is easy. The problem is knowing what is right.” But I’ve seen it quoted differently in different sources.

Does anyone have a definitive reference? Is there such a thing on the internet?

Here’s one site, and another, plus one more.

All three with different version. :stuck_out_tongue:

Anyone got the definitive one?
