STORY UPDATED: check for updates below.

Was the following quote tweeted by famous investor Warren Buffett or martial artist and film star Bruce Lee?

You will continue to suffer if you have an emotional reaction to everything that is said to you. True power is sitting back and observing things with logic. True power is restraint. If words control you that means everyone else can control you. Breathe and allow things to pass.

No, that's not true: the purported Buffett tweet seems to have originated on an impostor account. There is no record that Lee ever wrote or spoke those words.

An example of a printed version of the supposed Buffett tweet can be seen in this Facebook post (archived here) for example:

You can immediately tell the tweet is not real, just by looking at the image:

Warren Buffett's verified Twitter account is @WarrenBuffet, not @WarrenBuffetHQ. You can see the fake account lacks the telltale blue checkmark.

In addition to that a search on the real Twitter account in combination with part of the quote returns no results.

And the fake account seems to admit the quote was wrongly attributed in this (currently pinned) tweet (archived here):

You will continue to suffer if you believe in everything you read on the InterWebs or 'WhateverApp'
Especially true, if it's coming from people whose first name starts with N and last name with K

Social media memes also attribute the quote to Bruce Lee, including this one:

A spokeswoman for the Bruce Lee Foundation in Los Angeles said the organization has no record of the actor making the statement.
