Sure

If you only ate beans and drank water, you'd save a ton of money. But who gives a shit? You'd still die, just with more money.

I hate these little financial tips that are like - if you don't buy a cup of coffee for every day for 35 years, you'll save 250,000 or what the fuck ever. It's like these people don't actually live in the real world when they suggest things like this.
