You don't start a company to become happy, and most young entrepreneurs have to work at it for years until they get ROI, so if they went into it with high initial expectations, they're almost guaranteed to burn out before reaching their goals. Speaking of goals, you're confusing them with expectations. Having high goals and low expectations is generally the most potent mix to ensure that you're working hard. If you're working hard for an exam, but expect you'll only get a B, getting that A makes you happy. If you instead expect the A, and only get a B, you'll be unhappy and discouraged. We all know about that one star student who cried because they got "only a B".
