Back to the video in the OP…
The concept of not expanding your spending when your income increases is a tough thing to accomplish. It goes against our consumer culture.
But it’s a good message.
As I hinted at in the retire early thread, I have a hard time factoring in the home equity into “wealth” calculations. You can’t spend a house and if you want to live in it, you can’t sell it. Home equity is only wealth when your ready to sell. If the bulk of your wealth is in an illiquid asset that you’re unwilling to sell, are you really wealthy?
