The most successful people in history have used visualization to make the "impossible", the "improbable", and the "unachievable", a reality. Roger Bannister (4-minute mile). Albert Einstein (theory of relativity). Isaac Newton (law of gravity). Michael Jordan (law of gravity... LOL!)
They all used visualization.
So did Bruce Lee, Jim Carrey, Tiger Woods, Billy Joel, Oprah Winfrey.... and on and on and on.
I hope this inspires you in some way, to seek out your own best life.
