You can't change your body. Your body is supremely mutable. Your body is solid. Actually, at the atomic level, your body consists of vibrating atoms with lots of space in between. Bodies are a curse.
Bodies are an opportunity and a tool through which the inner soul can be discovered.
I am a victim of genetics. Genetics only reveal the make and model of your body. What you do with that body and that mind and how you care for them can be as powerful as your genes. People judge you by your body, first and foremost. Your self-concept is a powerful force that emanates from you and influences others.
