Some times it is wise to pause and reflect over the work at hand, even while in the midst of it, because in the involvement of rendering, certain aspects can be overlooked regarding 'keeping on track' with the work - all too often the forest can be forgotten in the intensity of caring for the trees, and even worse, one can forget that not all trees belong in that forest... even with the mindset of seeing themes everywhere, translating those themes to renderings and keeping them in context can be subverted by the possibilities in varieties and the need to trim the excess branches of some of the forest trees, if not indeed some of the trees themselves...
Sometimes it is cited as 'loss of motivation' - but that merely is a lacking of seeing within oneself as to why the rendering in the first place, and a momentary lapse of context in 'the joy of the doing' which is the primary reason for the doing... such reflections need not take long, tho can vary immensely, and the work continues, and another soon is there to carry on when the one at hand is completed... still, it is wise to remember that at times there is indeed a need for this, a form of refueling - else there is nothing but vapors to carry on, a prospect not desired, as the drop then would be horrendous, as also the consequences...
