Doesn't make mathematical sense unless he earned a whole lot more than $40K.
If he started saving at 18 (assumption) and is a millionaire by 30, assuming he makes a steady 7% on his money, he'd have had to make monthly deposits of $4,488 without missing a month.
If he earns $40K/year as stated, that's only $3,333/month income....before taxes.
He'd have to earn at least 26% interest and not spend one dime on living expenses to make it work on that salary, after accounting for federal taxes and FICA alone.
Or have several grand/month in additional income from his side jobs (at least another $1,100 towards savings + 100% of his living expenses) which would mean although his "salary" was $40k, his actual income was substantially higher. Which is cool... but if that's the case, he's really not a millionaire at 30 on $40K.
Depending on what he did with rental properties and investments, its possible that despite his $40k salary he's generated enough passive income to become a millionaire. That said, the story is certainly misleading. You're not really becoming a millionaire on $40k a year if you're earning another $25k in investment income.
My goal personally is to have no debt, and $100k in the bank (not including retirement accounts) by 12/31/2011.
I've made a lot of progress on the first part (all I really have left is $15k in student loans) the latter... well that will take a lot more work, but I'll get there.
