Eckhart Tolle
This is one quote that really applies to me. I spent and often spend most of my life in my head with my thoughts that never seem to turn off. I read everything I can get my hands on and it wasn't until I started to read the work of Byron Katie, Eckhart Tolle, and others like them that I started to question the thoughts that I had and am having. Do these thoughts bring me any peace? Do they help my life in any way? If they are meant to protect, are they protecting me or causing me unhappiness?
