When describing me, Tracy often refers to a well-known concept of physics: 'inertia.' As Newton avers in his first law: 'An object that is not moving will not move until a force acts upon it. An object that is moving will not change its velocity until a net force acts upon it.' In other words, depending on what's happening in my life at any given moment, I can either be the laziest human being on the planet, or the busiest. I'm perfectly content to do absolutely nothing until I'm catalyzed by some person or project, and then I go nonstop until some countervailing force acts upon me, and I revert back to static mode.
