I think most "self-help" experts even from the 1800s would agree that one's iron will eventually turns into ambition, and that it is the most linked trait to both success and failure. Galileo was set apart for a physician, but when compelled to study anatomy and physiology, he would hide his Euclid and Archimedes, and stealthily work out the abstruse problems. When shortly imprisoned in his cell, he would even experiment with the straw laying around to make new discoveries. I just don't agree with hierarchical rank at all. It's the most obvious trait to the common person. But it doesn't include the context of how people got to that level in the first place. Mostly because many of the famous stories of great breakthroughs in science, invention, wealth, etc come from stories of early adversity. There are plenty of stories of those who inherit their hierarchical rank and then lose their fortunes and place in society because they have no such ambition. Hierarchy is determined by ambition.
