BBNaija celebrity status normally expires in 12 months. The reason ex-BBNaija housemate Bisola landed an endorsement deal recently (2019) is because she is now solidly into music. But is it every housemate that has an artistic skill? No.
If some housemates should release an album, people will pick race.
So, learn the lesson. Do what Miracle Igbokwe did with his BBNaija prize money: further your education. That may mean that you cease being a celebrity as you become an office/field executive without much fame. But is that not better than wasting that money on a project when you know you don’t have the talent for it?
You can take a leave of absence from your working place, further your education with your prize money, endorsement money, gift money, e.t.c., and then come back bigger financially.
Note: This is just an advice. Commonsense is not always the wisest choice. So, just think about it and then make your own decision.
