As far as I'm concerned, the ideal source of income would be something with no set hours, that I could leave and come back to as I please. In other words, if I decide that I'd rather play video games for a month instead of earning money, it won't prevent me from earning money the month after that.
You can easily do that with a business, if you set it up correctly, and you are willing to spend money to make money. More to the point, though, you'd need to actually want to have a business, a bit more badly than you appear to want a job. ;-)
I've always heard that having a successful business is usually an awful lot of work, even more than being an employee. At least, that's what my father says, and he's almost always right.
