Calculating if it's better to pay off the mortgage or invest it, if I win the $1mil prize of the Powerball, even though I don't have a ticket. I may buy one since the jackpot has surpassed my $1billion limit.

No use fantasizing about winning that, though since I'd just take the annuity and make more money than I could ever spend every year for 30 years.

Edit: I bought a ticket tonight and did not get a single number even close. Ah well, back to the grind tomorrow.
