Would you have more money if you didn't buy coffee? Perhaps marginally more, but it's a rounding error in the grand scheme of things. Stop focusing on the little things that don't matter. Buying coffee is peewee stuff that just does not matter, and you have these so-called financial "experts" focused on this kind of stuff, alienating everyone in the process. There are so many other things you should be focusing on to improve your financial well-being.
