That's another thing about working for yourself. When something doesn't go right, it's all you. If you fail, it's all you. There's no one else to blame and that can be a tough pill to swallow. Although, that doesn't stop people from blaming the economy, the employees, the customer base and anything else they can think of. Hell, I heard a guy say business was slow because the fair was in town.
"You can make money or you can make excuses, but you can't make both."
