To check and change thoughts and feelings constantly is to ensure positive change. The one who has a constant check on his own thoughts is able to bring about a change in them. So thoughts when changed to positive bring about change in words and behaviour too. There is no negative waste, or even ordinary behaviour. There is speciality revealed in every act. When I am constantly aware of the quality of thoughts I am creating at each moment, I can keep a check on them. My thoughts are not just positive, but powerful too. These powerful thoughts create a positive impact and I experience constant success.
