It has to do with the intention. If someone is planning to redirect these £€$ 5 per day (150 per month, 1825 per year) on something else, e.g. algo forex trading with a safe 0.20% profit per day, then those 5-per-day will become 650k in 10 years. I like my coffee just as the next guy, but if 'depriving myself' from the daily coffee will help me get to my F.I.R.E. [1,2] ten years sooner, then I am dropping it. By the way I have quit drinking coffee (only decaf) and juices, but it was more of a health-choice than a financial one. But of course everyone decides what to do with their £€$ 5-per-day :) [1]: https://www.financialindependenceretireearly.com/ https://www.financialindependenceretireearly.com/ [2]: https://www.investopedia.com/terms/f/financial-independence-retire-early-fire.asp https://www.investopedia.com/terms/f/financial-independence-... Edit: also.. converting that 5-per-day to 650k in ten years, can make life SO MUCH easier when your kids will have to go to University.
