If someone is truly desperate, they would try to work any job they could find. Simple as that. If you aren't willing to do what it takes to pay bills, then you aren't actually desperate.
Too bad that sometimes situation occurs not the way we expected it. It could happen while we don't have any money in our pocket and we don't have a job. So the only thing that will be left for you to do is either find someone you could owe, or force your self to sell something that you don't want too. When we are desperately in need, it means that the thing happen unexpectedly. Simple money problem aren't desperation.
