I would say that the worst decision would be to borrow a huge amount of money if you aren’t completely sure that you will be able to pay it off as soon as you can. You would find yourself in a vicious circle in such a situation, and you will always work and earn for something that has passed. You know, you will find yourself like running out of time, working all the time, and never having enough money. One more problem here is that people tend to spend someone else’s money much easier than their own, as the psychology claims. So, they won’t think clearly.
