If someone tries to steal your idea, who cares? The only thing that matters is providing value to others. The first and best way to improve your feelings of worthiness is simply to provide value to others; be kind to others as well as to your future self. Be of service, which means providing value with no expectations of receiving anything in return. It contains the requirement that you give unconditionally. Giving with expectation, as my friend Bob Proctor says, is trading and not real giving.
