We also create our realities in a much more tangible way with thought as well. Our subconscious mind is designed to bring us our predominant way of thinking (or beliefs). It causes us to do things that lead us to our beliefs. If we believe most people are nice, we will subconsciously do things to not only witness examples help with assignment  of that reality but to draw more nice people into our lives as well. If you fail to direct your thoughts they default to input, which is simply your thought reaction to circumstances and experiences, and often the emotions associated with them can be unwanted.
