the most successful ones postulate a vague future date for the apocalypse.

this gives them time to generate momentum and acolytes.

by declaring the imminent end of the world you provide little incentive for people to flock to your cause, engage in polygamous marriage to the cult leader, and hand over all their personal wealth.

just think if you're wrong about the world coming to an end next week, apollo? you need to plan for the future.

Open an IRA. Stop smoking. Lose weight. Find a nice girl (or boy) and settle down. Even if the world does end tomorrow, you won't be at a loss for having lived as if there was a future.
