There is so much information that comes to our five senses. Everything we see, hear, touch, feel, and smell.
It is far too much information for the brain to process so the brain filters out information. This is where your beliefs come in.
Beliefs are the concepts, ideas, theories, and assumptions that you think are true.
Your brain will use these beliefs to help determine what information you become conscious about.
If you believe people are friendly, you will notice people acting friendly.
If you believe people are mean, you will notice people acting mean.
In many ways, we get to choose the world we want to live in.
Choose your beliefs intelligently to best serve you and the world you want to live in.
