Imperfection

Accept lost sales willingly 
Accept failure as the human condition
Accept your own fallibility 
Nor be overly concerned with wins and losses
Imperfection comes with being a human being.

Perfection is an ideal never obtained, yet always in mind. 
Surrender Yourself to your own limits
Then you can be trusted with the tools for making sales.
Once you appreciate your strengths and weaknesses
you begin the journey to becoming  the Master Seller.
