There are only two types of people:
If you read The Millionaire Next Door, you will see example after example of how many rich people look completely normal in terms of how they live their lives. Famously, Warren Buffett still lives in the house he bought decades ago.
The flipside is people like Mike Tyson, declaring bankrupcy after blowing hundreds of millions of dollars.
The thing that worked for me is to see investments as a kind of purchase. I tend to think about what I want to buy, and what it will do for me (produce interest or dividends, mostly). Effectively I have replaced shopping for gadgets (something I used to do a lot of) with shopping for investments.
How do you think about money? Do you get excited about saving and investing?
