What is finished? outdoor paintings started on location

Two questions haunt me. One, I keep asking why I become dissatisfied with so many paintings I once considered finished. I am puzzled because this change in judgement is made in light of my desires to make, to be done and to go onto new experiences. Could it be that I depart from a prescribed and predictable finish? My approach is to paint only what is necessary to communicate. I want to make my emotions of the moment come forth through my subject or abstraction. I could be in a different thinking mode in years to come. I become my own audience and thus demand more clearly stated visions. I like the random order of nature and want to approximate nature's energy. If the painting has gone through labor and torment I want to make it more natural than my first markings on the paper. The second question is why am I becoming less interested in selling. It would be nice to have money to buy materials and cover my expenses. Could be because there are fewer sales today and in defense I just say I don't care. But I was growing less interested before the recession. Could it be because I have had wonderful sales in the past where my art work was enjoyed by someone who I met and cared about. Maybe I am less interested in selling because of my organization of my work to keep some from each year and to recycle the rest into new works. Today I organized my work on paper by subject and labeled the shelves of work. I am going to constantly accept a or recycle my work so the total growth of my collection remains constant.
