This paper reflects my thoughts and experiences regarding influences of positive human will power on successful WLM (not specifically but appropriate for our conference) in public water utilities. Resolving problems in Water Loss Management (WLM) involves holistic approach, and I came to a point of understanding that despite available knowledge and technology is still evident slow and harder then expected integration of advanced WLM partly due to continuing reduction of positive and constructive will power among water utility personnel to make necessary changes and improvements. Aim of this discussion is to present you following; how to define will power, what influences will power, how to get it, and why use it in positive way, because will power is related with all aspects of successful WLM; education, management, cooperation, continuity, adaptation, focus, innovation, ect. All point of observation are related with psychological aspects regarding peoples will to make changes and physical manifestations - successful WLM, but also satisfaction with ourselves not only in our profession or job but in life generally.
