Most Nigerians struggle financially in January because they spend more buying new clothes they already have, making more financial expenses on traveling, which some are not really relevant, over spending on food which is even more than a 6 mouth budget. instead of making plans on how to renew house rent store rent paying of school fees by January e.t.c
However, I can say that you are talking directly to the low income earner, because those who already have money cam not spend like a because of a house rent, shop tents or school fees as you mentioned, Nigeria is a wealthy country that have enough citizens that are wealthy, so if you think that people are using their last money to entertain them selfs this celebration season, i think you are very much wrong.
Although, we have Bitcoin, one can invest in Bitcoin ones it's the early part of the year, I know it might be hard to get the money to invest into Bitcoin but I think it is still good not to invest when you don't have the money to invest.
Still, there are also a lot of opportunities that can provide money for you but if is just left for you to make the right decisions by working in a very smart way so that you can get money to create a better opportunity for your self.
Lastly, if you can not afford to do something don't just force your self to do it, more especially if it will not be of any benefits for you, and again, you talked about traveling as a waist of money, but that's not true because i see travelling as part of learning, the more you travel, the more you get more experience.
