Marilyn vos Savant, the person with the highest recorded IQ, was once asked "Can you tell within a few minutes if someone will be successful?" Her answer (and I'm paraphrasing here): "Absolutely. All I have to do is figure out who they associate with and what they feed their mind."
Really simple. If you want to be successful: 1) hang out with successful people, to absorb their wisdom, habits, and attitude, and 2) feed your mind with positive knowledge.
