You cannot plant greatness as you plant yams or maize.
Who ever planted an iroko tree—the greatest tree in the forest?
You may collect all the iroko seeds in the world, open the soil and put them there.
It will be in vain.
The great tree chooses where to grow and we find it there,
so it is with greatness in men
