Being great in one area, requires sacrifice in others. 

Depending on your role, abilities, responsibilities, and eternal purpose – these sacrifices can change tremendously. 

Greatness (or excellence) means there is no room for improvement. 

The biggest fallacy is assuming greatness in all areas is possible.

You can be good everywhere if you work hard, but will not be and cannot be great in every area, that is why you must choose where you sacrifice, what you sacrifice, and who you sacrifice for that chosen greatness.
