This quote shares the spiritual side of Anthony Robbins and there are many other quotes similar to this that basically mean the same thing about being appreciative of what you have in life instead of constantly striving yourself for something. When you realize all that you have in life already or how fortunate you are compared to others you can realize what you strive for is already present in your life.
Fear usually manifests itself when you think you are missing something so it is important to realize what you really do have in your life.
Abundance also appears when you realize how much you have when compared to someone else. One time I was meditating by the lake and I had an overcoming feeling of Joy and realized that I had everything that I ever needed just sitting there listening to the waves. I did not think of any possessions in my life or people in my life. Just sitting there listening to the water was all that I needed in my life at that very moment.
