We ourselves place limits on what we are able to achieve as well as our families, friends and society in general.
While we have the ability to create happiness and peace in our life, we often use that same ability to destroy ourselves and undo every step that we had struggled to achieve. One little mistake, a person can lose touch with the direction they were taking and not be able to find the courage or the will to begin again. We get tired, tired of trying, while forgetting that it is the effort to continue that is often the most important challenge in life and not the progress that we were expecting or expected to make.
