We are all magic in a sense.  We knew that when we were small children, but as we got older, we listened to and accepted the limits others like friends, parents and teachers put on us.  The limits they put on themselves in the same way.  But are those limits real?  In many cases, the answer is no, they are not.  They limit us nonetheless because we accept them.  We believe these limits and that belief make them real for us.  Our brain has to filter out the information it processes so lees than one percent of it enters our conscious mind.  And our subconscious filters select what to send to the conscious based on our beliefs.  So beliefs become self-fulfilling.  The person who believes he is always sick and week weak will never see a way to get strong and healthy because that information is getting filtered out.  The Atheist will never see evidence that God exists because that information is being filtered out.
    So if you want your life to be different, to change for the better, you need to change those beliefs that are limiting you.
