Thoughts become things. 

Words, physiology, and tonality
define our Language.

Joyful, loving people use joyous anguage.
Unhappy, depressed people use depressive language. 

If you are in anyway not happy about a situation, environment, relationship,
change your language - it will change your world. 

To simple?
Your thoughts, mostly subconscious, drive you. Those thoughts create your language and thus your world.
