One-ish. I've got my brother interested in personal finance, but he's young (18) and is more interested in the Millionaire Fastlane line of thinking than the "long" frugal method. I showed him my investments after only 3 months of working and living frugally and he was impressed, but not so much that he's ready to give up MFL. That said, at least the kid is thinking about wealth and retirement, which is a win in my book.
