RE: Hello?
Although I totally admire the attitude, it seems that it could be one of those things that is easier said than done for many. Definitely have to be brave and then quickly accepting when you realize you took a vastly wrong turn in the poor over. I suppose in being totally realistic, once you DO go over, there is no going back, so you might as well not stay and dwell on it... .but go forward. Makes sense, but much of art is emotionally based, so it is not always so easy.
At the time I started the one I showed, it was a paint over of another one whose direction I wasn't happy with..... so swish, swish, over the top came a new beginning. Some are obviously wrong and are easy to let go.... others, take some pondering time.
I nearly never have a vision of a finished piece when I start one, so most of them sway, wind and turn in various directions before ending. I thought I KNEW this one wasn't done, but I liked the start at the time and now it has been quite a bit of time so there is no continuance of feel. Time to get a new feel... right ? LOL
I know there is no rule or time or anything that tells an art creator when something is done, it is more a feel or simply a personal decision.
