  1. Look at the way my acquaintance Wesley Virgin's biography begins with this SHOCKING AND CONTROVERSIAL video.

    Wesley was in the army-and shortly after leaving-he unveiled hidden, "mind control" tactics that the government and others used to get whatever they want.

    THESE are the EXACT same secrets many famous people (especially those who "became famous out of nowhere") and the greatest business people used to become rich and successful.

    You've heard that you use only 10% of your brain.

    That's really because the majority of your brainpower is UNTAPPED.

    Perhaps this expression has even occurred INSIDE your own head... as it did in my good friend Wesley Virgin's head around 7 years back, while driving a non-registered, beat-up trash bucket of a car without a license and with $3 on his bank card.

    "I'm very frustrated with going through life check to check! When will I get my big break?"

    You've taken part in those types of thoughts, isn't it right?

    Your success story is waiting to happen. You just need to take a leap of faith in YOURSELF.
