My best friend's mom has started several personal businesses. She was reluctant to interview because none of her businesses have lasted very long (she's a stay at home mom with four children). I've seen her in action, though, and the woman knows what it takes to get a business going.
I emailed her, called her twice, and emailed her again. After a busy weekend, she was able to email me back (the phone was dead).
So, rather than try to sum up her story, I will transcribe her email below because her explanation is impeccable.
