List all of the characteristics of a leader that you can think of. Done? I bet you missed the 2 most important ones.
Humility and pain tolerance.
We all have ambitions to achieve great things. Some of us want to change the world. But for what purpose? It could be argued that most of our "leaders" are not working to benefit their cause, but rather to benefit their ego. They do their best to hold themselves higher than others.
However, great leaders must be willing to humble themselves and tolerate pain in order to achieve the best results for their team. A leader who wants to do the work by him/herself is arrogant, not selfless and not a good teammate. A leader who can not tolerate discomfort will crumble under pressure and find ways to blame other people for their mistakes rather than owning up to them.
It's important for a leader to build their teammates up and trust that they can perform at a high level. One person can not do a job better than a team built of members with many talents.
