Your thoughts become things. What occupies your mind manifests itself in your daily life. This comes about as a result of you, often unwittingly, investing your energy - and the energy of the universe responding to your very own input. Unfortunately, your default state of mind gives credence to the "voices in our head" the random thoughts that pre-occupy our minds, like squatters. It's up to you - and you alone - to ignore these thoughts. They will never go away - but can learn to not give them your energy - and, rather invest your energy in living life to the full.
