Personally I would spend all this excess emotional energy and put it into either your startup, or a relationship with a significant other. Or exercise.

Sure, there are plenty of stories about people who were desperate and became successes. You never hear about the hundreds of thousands of people who were desperate and became abject failures. There are also people who are successful who were born with silver spoons in their mouths. So I would not make any type of correlation between some extreme emotional state and being successful. If anything, it might make you squirrely and detract from your obligations at your startup.
