Quotes from the same author

In this fast paced world it is too frequently the case that people accept what society, family members and the authorities, whom nobody ever seems to question, believe regarding how to live their lives. And yet, the happiest people I know have been those who have accepted the primary responsibility for their own spiritual and physical well-being - those who have inner strength, courage, determination, common sense and faith in the process of creating more balanced and satisfying lives for themselves.
 Ann Wigmore
Every thought has the power to bring into being the visible from the invisible. It is absolutely necessary for us all to understand that everything we think, do or say comes back to us. Every thought, word or action- without exception- manifests itself [in some way] as an actual reality.
