As other people have said, if you really are desperate then it masks your worldview. One can tend to act differently, because the resources/outlook is limited. Sometimes this works, but more often it doesn't, because typically your desperation makes you focus on getting the next meal, the next bit of money coming in. This takes you away from giving all your focus to something great without distraction.
There are obviously counterexamples where it can be used as the fuel to do something and that works out, and those can be inspiring. But if you want to do something great you actually want to do something great, there's your fuel. So then cutting away anything that takes you away from your goal helps enormously.
