Check out classroom teachers. The third implication in my example has to do with negotiation itself. Life is negotiable. Think of driving in any congested area. I live near one of the most car and people congested areas in the country, and by simply standing on the sidewalk I can observe life as negotiable.
Money is also negotiable.
That ain't hay. Time and money together are also negotiable. Suppose you are in a negotiating position, with a lot of other people around a table. You are part of the action, as a negotiating person, at the same time you are keeping track of what everyone else is doing. You are BOTH inside and outside of the situation.
