There is one difference, they didn’t have The Great Depression to look back and learn lessons from, or the internet to inform/scare/spin/etc.
If the dow retreats below 6000 again, I’m going all in, my money, your money, maybe I’ll steal some money or sell body parts/fluids and put that money in. But I’m fairly certain I missed it, sometimes you just have to open a bottle of wine and accept that you aren’t perfect, that fear gets the best of you sometime, that you might be better with 5 or 10% less brain cells, so you might as well start dumping some now, it’s only money, by the third glass it doesn’t matter so much, even if only for a few hours.
The same theory works in football, I can want the patriots to be bad, I can read blogs where people with credentials say that they won’t beat my beloved bolts, we can look at charts and history, we can look at blue mohawks, but at the end of the day, Brady is back, and that is gonna be bad for everyone else in the AFC. At some point you just have to accept it and find a way to enjoy the ride, dammit, that realization is gonna take a fourth glass to make the pain go away.
