Nigeria is in a very big problem. What is problem, " problem in this context can be seen as a state of no solution". It is very clear that nobody has the solution to this country except God almighty for now.
Though every problem have it solution but the problem of this country Nigeria is so big. Even most of our politicians knows how big the problem is, instead of them to be offsetting it small small they rather go and add more problem to the country because of self centeredness.
Most of our politicians knows that someday they will not be here and their children won't be here either that is why they are doing things regardless of anything, they don't care about the welfare of the country but rather they add problems and also benefit from those problems.
Below are the characteristics of someone I think/feel can help this country.
1. A tolerant person => someone who will not listen to what people will say until he is done achieving what he wants to achieve for the country, it is very true that people will criticize when you are doing something because of how you start not until they see the result of what you were doing. Most people end up on the way because they can't take what talk about them any longer.
2. A person who takes advice, you can't be correct all time
3. A person that is soft in mind, I mean someone that can never think of hurting the country in making a decision, someone who understands the feelings of the people
4. A creative minded person
etc
well OP, there's no problem that can't be solved, the thing is, are the people there interested in solving the said problem?. The problem of Nigeria its 50% the politicians, and 50% the people.
The politicians are bad and corrupt, yes, but they cannot carry out their corrupt practice alone. They must carry it out through some of the masses whom are loyal to them. They've intentionally kept the masses hungry in order to rule effectively by offering peanuts instead of real infrastructural development. The greatest heartbreak of all is that some people are still much hungry and they have the mind to be chanting the praise of these politicians whom are taking advantage of them, instead of ignoring them and working on electing a more competent candidate in the next election.
The people are thereby learning from their masters and in the office, you can see corruption everywhere, starting from the managers and heads whom employ ghost workers and leave the bulk of the work for very few vulnerable juniors. The workers themselves lacks dedication and wouldn't just give their best which sometimes is as a result of low motivation from the employers or senior colleagues.
Even in the armed forces, the so called uniform men have turned away from their job and task of protecting the citizens to killing them. Nigeria needs a reorientation in all angles cos now corruption and evil is now seen as a way of life.
