We are the Creators of our world. Although, we might not believe this, we truly are life's creators. How we act, behave, and respond to events and circumstances creates how those around you, react, behave, and respond to you.
If you are not crazy about the world around you is, the only what to change it, is to change your thinking. This is not an easy task, or quickly done, unless you experience a significant life changing event, which profoundly changes the way you think, behave and/or what you believed to be true, but no longer is.
You do not need to have a life changing event, in order to change your thinking and beliefs. But little changes in one's life, unless you look at life in a different way then what you have perceived to date.
For most of us, changing one's thoughts, beliefs, or understanding of one's life, may happen slowly over time.
Some of the changes I made were from profound events, others slowly changed as a grew older and more experienced.
