Nigeria is a country that is highly favored by God with the endowment of natural resources.
Nigeria is said to be the giant of Africa in populations and  natural resources, but Nigeria is not living as the giant of Africa.
Nigeria is blessed with so many natural resources but the leaders lacks the wisdom to manage the resources. Nigerian achievement cannot be compared with other African country and the world because there is no thing to write about the achievement of Nigeria.
Are we to compare Ghana with Nigeria? No, Ghana is far more better than Nigeria in terms of achievement.Ghana has an uninterrupted power supply, Nigeria has no stable power supply.
Ghana currency is higher than Nigeria currency.
With all this I have mentioned Nigeria achievement cannot be compared to other African country and the word achievement.
