Excuse Number 5: I don't have an idea. Everyone loves to tout how 'ideas are shit!'. But, when you spend a lot of your time trying to spot problems, only to find out every one of them has been done already...

Excuse Number 6: Health Insurance. I've saved enough to cover my mortgage & living expenses for a year. What I haven't saved for is an insurance plan that will not bankrupt my family if one of us has the unfortunate timing of getting in a car accident or gets cancer while I'm trying to start a business.
