It's so sad what you have shared what is happening in your country.These days in Nigeria is very hard for you to get your dream job but as a young talented man who is very dedicated he or she can get his dream job by being focus and dedicated so what he loves me most. However these days if you end up doing what they never studied in school because that is where life let them.
I think that is also happening all around the world. It's really very hard to land in the dream job you are dreaming of.
