Why do you push yourself so hard?  What are you trying to prove?  Who are you trying to please?  Everyone?  And at what cost?  Have you noticed the flowers around you?  Have you stopped to smell them?  They are not rushing and doing and trying.  Simply by BEING they are serving and fulfilling their purpose.  You can learn a lot from a flower.  How beautiful you are simply by being you!  You need not prove this to anyone.  Simply be, and let others see your true nature.
