The secret of Buffett is how well funded he is. He makes almost as many mistakes as an average investor, but where the latter loses and fails flat, Buffett loses and moves on without notion.
So, if you fund an "average" investor with enough money, he/she would become as successful as Buffett? This is like suggesting that anyone can become a Napoleon -- all you need is an army under your command.
can be an important factor, in my experience
Buffet is a really decent fella, I've read "The snowball' this is a very interesting and exciting book.
