"Be the change you wish to see in the world", said Mahatma Gandhi.

"Holding onto anger is like drinking poison and expecting the other person to die", said the Buddha.

Except.... apparently they didn't. Both quotes are mis-attributed.  There is discussion about who might have said them, but it wasn't Gandhi and it wasn't the Buddha. The debate about mis-attributed quotes sometimes gets heated: people hold onto their anger and almost certainly aren't the change they wish to see in the world.

You probably think it doesn't matter, but it matters enough.  Enough to have people spending time thinking about it, debating it, and missing the point of the quote.

Two observations then:

First, historical sources are almost all unreliable.
Second, when you dismiss something - "oh, it doesn't matter" - then you're almost certainly wrong. It will matter. Just enough. To some people.
