Depends on what you mean by 'good', but if I were to guess it would be the following factors:
2) military prowess;
3) savvy poitician or shrewd personality, at the very least a good people manipulator;
4) a good manager, or at the very least good at knowing who are good managers;
5) Knowing how to prosper in times of peace or knowing how to win and plunder in times of war.
