    > I read that it took 16,000 88 flak shells to bring down one bomber. I infer the success of the flak was due simply to quantity. I am not trying to be pedantic, just wondering out…

    Build up my savings to the point where I can live comfortably for 2+ years without a paycheck, or 4+ on a tight budget. DCA into ETFs with the leftovers. Buy a little bit more non-…
