People look at me strangely when I say this, but there is no way in hell I would want to win that kind of money. It changes things forever, and I don't think for the positive. Relationships get destroyed. People go broke because they don't know how to be rich. You think you will do all these wonderful things, but you are just as likely to lose all motivation in life because you don't need to do anything, you have no responsibilities. You'd be much better off winning low and taking the yearly payout. You're comfortable, but can't be ridiculously indulgent.
That may be true of people who have no ambition or drive and only work so that they don't starve. Then again, that is probably the demographic that overwhelmingly participates in lotteries.
