Can’t. My brain doesn’t go past a certain figure for myself. Just fizzes out.
I had a neighbor as a kid that could count all the ways she was going to spend One million dollars when she won the lottery. Down to the penny.
She was not likely to ever win; it was a fantasy exercise for her but it seemed like a waste of time and lots of weekly disappointment and I decided I wouldn’t do that kind of thing.
Planning? yes. And planning big? Yes. Going just outside of reasonable? Absolutely. But when it’s that level of all those money amounts, my brain goes “bzzzt – don’t”.
