Pascal's wager Live a good life. If there are good and just god/s, then you will be saved. If god/s are not just, then you shouldn't worship them anyway. If there is/are no god/s, then you will live well in the memory of others.
Stop Animal Cruelty Now! Although I totally agree with the "Stop Animal Cruelty Now" part of this, I don't think that the comparison to "just a human" is fair because there are so many good people who do good things.
