Brushstrokes

Looking at my 4 year old the other day carefully placing identical blobs of color onto a piece of paper, (due to his under developed fine motor skills of course), I began to wonder whether this is the right way to go in order to achieve balance in a painting. That is should I carefully continue with a chosen direction and method of applying a stroke, a la Van Gogh or the Pointillists, as opposed to acting on impulse and taking cues from hand movements? If you simply follow your instincts, then the piece shows intensity but also chaos and instability. If all brushstrokes flow simultaneously, then there's serenity and the eye is calmer when it moves around the work. Question is what do you want to achieve, and is this result what you'd be happy with for the moment, or is it good enough to live with for a lifetime?
