You really are sure you wouldn't do anything different if an oracle told you it is actually your last day? There are so may possibilities for making the most of it.

You could take out every bit of loan or debt accessible and transfer all the money to charity. You could burn down the HQ of an oil company.

If you live in a country without the rule of Law, like Russia, where known killers and criminals hold positions of power, you could try your hand at assasinating one of them.
