For those who require a more stringent and limiting structure in order to limit destructive behavior, lower emotions such as fear, anger, and guilt may be the only useful motivators in the earlier stages of learning the lessons of life. These, attached to thoughts, form beliefs, which our ego uses to establish identity, place, direction, and purpose.
Emotion relates directly to our desires as well as to our ideals.
These learning processes involve trial and error. More pain to one degree or another, whether it may be so mild sometimes we laugh our way through it, or so intense we go into some form of shock and suppress the memory of it. As we are becoming more sensitized to the cleaner fuels and more efficient operation of the engine, we also notice more acutely the drag-effect that the baggage creates, and its effect on overall efficiency of the vehicle. And we become more and more motivated to clear the baggage out. We have to get our hands into the grease some in order to get the gummy stuff out.
