The brain does not differentiate between what you see with your eyes and what you see in thought.
If you imagine (even something that seems unattainable) something often enough and long enough, your brain will think that this is your reality.
If the '' reality '' imagined does not correspond to the '' visible '' reality, it will make ALL to find the evidence that what you imagine is true.
Your eyes see only 10% of the reality around us. The brain, like a radar, will search for evidence that what you believe is true!
Hence the importance of visualizing!
ALL Olympic athletes visualize!
ALL the people who have the most success visualize!
Don't you want to do it too?
