What is happiness and is it really outside sources which could make a person happy?
When some thing good occurs in a person's life or to you, happiness ensues. However is this actually this outside source which allows you happiness or is there some thing much deeper within that determines if you are happy or not really?

Think of this, can THINGS tickle the human brain in order to stimulate joy? No, it's a direct end result of your method of thinking about the THINGS which results in joy.

Simply by changing the method you actually think you really can transform your life. This is not really some new age nonsense, this truly is effective and it's not difficult to reason exactly why it works. Our thoughts are so busy with material issues that it's hard for us to be able to notice the real world.
