You are not meant for greatness. No one is! However, you are capable! We are all capable of greatness! No one is meant for anything, we are all just capable of everything. And we have free will to choose if we are going to be great!
There is a significant difference in being meant and being capable. Being meant for greatness means that you have no responsibility for it. Being capable for greatness gives you the responsibility to choose if you are going to live by your full potential, or you may want to do something else. It gives you the opportunity to make your own destiny! And being meant for greatness, by default takes the essence of greatness away, because greatness is achieved not given!
