What would you do if:

1 $10; put it my pocket, use it next time I’m buying cannabis because they only really take cash.
2 $100 It would either be a new power supply or computer case. I’m slowly building a new computer, already have the mobo + CPU
3 $1000 now we’re into the real money territory. Tempted as I am to blow the whole wad on my computer parts, I’d probably buy a steam deck and a nice set of headphones, steam deck is about 600-700, a good pair of headphones around 200, left over would go to computer parts
4 $10,000 That’s a lot of money. I’d take half and put it away to go on vacation, we’ve been talking about Yellowstone, 5k would pay for that trip. With the rest I’d still get the things in the previous two tiers. I’d finish off the computer build with hard drives and a graphics card. Finally, I’d get my window fixed and have some body work done on my car.
5 $100,000 I’d pay off all of my debt, starting with the house. I’d probably take $10k and get everything I previously talked about. The rest, rainy day fund. I had one before I bought the house, but so far every time I’ve gotten close again the house has needed it.
6 $1,000,000 That is really a lot of money. I could pay off my debt, my parents debt and take us all on a three week trip to the Netherlands and still have 70% left over. I’d take 50% and put it into some sort of dividend yielding investment, last I checked I could give myself an assured income for the rest of my life of enough for food, shelter and tech gadgets.
The other 20%, roughly 200k. I’d buy some land in the mountains, get a cabin or some such on it. Then I’d go spend about a year living up there, because I would really like to get away from the city I’m in.

7-$10,000,000 I’d retire completely there. I once calculated how much it would cost to do everything I’ve ever wanted and still have enough to live on, and this is coincidentally that amount. I might still work, but probably in something I’m passionate about, not something that makes a specific amount of money.

The question might be what is different between 1 mil and 10 mil, and the answer is unintended incidentals. Keeping my medications going, keeping my cars going, and having children are going to eat up a couple million over the next two decades.
