Our ability is great, but our motives are petty. We the people have seemingly always been able to accomplish just about everything we want to accomplish. What we want to accomplish, unfortunately, doesn't amount to much.
What do we want? We want to matter. And, for the vast majority of us, we think that mattering comes down to amassing fortune and glory. Through our various gifts, our strength, our intelligence, our charisma, we seek to influence those around us so that our will is done. We quickly learn what makes people take notice, what people value, and we pursue it.
