There is a solution for that dilemma (of not knowing the future): Plan for the worst, but hedge it so that if the worst doesn't happen, you still have no regrets. Examples:

1. Kill your TV: spend more time with God, friends, family, neighbors.
2. Invest in yourself: learn how to build, make, hunt, cook, heal, pray, and think.
3. Become more self sufficient: be able to make your own water, food, power, tools, clothes.

You profit either way: if no collapse happens you have a more meaningful life. If things do collapse, you "just" have harder times, you aren't completely devastated. You also get to be a part of the solution on the other side of the bang.
