How do you establish the definition for greatness. With what criteria do you rate this. Is it the amount of money you have in your bank account? Or is it the number of territories you control? Is it the number of people you've slept with.. ?
LET ME TE YOU WHAT I KNOW
The only way we can achieve greatness is actually by lending a helping hand. Would you build territories yourself.. Would you lay brick on bricks solely by your expertise?
This is totally impossible. You need someone's help at every point in your life. This means that our growth is entirely intertwined with others. Therefore achieving greatness totally depends on how many life's you affected on your voyage on earth. Just as you need people to help you grow, others are looking up to you to help them grow. This is the true definition of greatness... Helping people around you achieve their dreams..
A GREAT MAN SEES HIMSELF AS A LIGHT TO OTHERS PATH. THE USE FOR EVERY SUN IS TO BRIGHTEN THE EARTH. Treasure
The presumed greatness you achieve at the expense of other people can only be counted as a minus. A mansion with a thousand rooms yet no sound of music from its windows, no cries from a baby, no light shining on the lamp stand. Only cobwebs and rats living inside
Would you rather be rich and be remembered for evil or be rich and be remembered for for good..
Will your children proudly call out your name in the public place and tell people.. I am a direct descendant of Treasure.. Or will they harden their minds with shame at the mention of your name.... Make the decision to be great today. Affect a soul. 
There is also a hard working story behind all the great man
The dreams they all achieved, the battles they've won is nothing compared to the will of their creator... And that is loving others..
For loves sake, everything on earth still exists. If not. Nothing would have existed. Even the gold and treasures that made them famous
What's the use of a million dollars when no one can testify of the love you've shown
Your hard work is necessary. No food for lazy man. But after getting food for yourself. What you do afterwards with the left over makes you great or not
