Warren Buffett proves everyone can be rich?
Isnt that like saying Eminem proves everyone can be a successful rapper....
To be fair, he didn't say everyone can be rich. He said "successful", which can be subjective. You don't need to be a millionaire (let alone a billionaire) to be well off.
That being said, not everyone can be successful. I used to think everyone could just by working harder. I was wrong.
Self made person = intelligence, hard work, leadership, luck. How often you see all of that on one person?
