I have to agree. The majority of home/personal economists (that I have encountered directly or via their books) state that if you're trying to "save your finances" by quitting your Starbucks coffee, you're already too late and are predominantly screwed.

Wealth is created by investment, not savings. This investment includes investing in yourself (education, even if it's not via a traditional University program but by career training or online learning of a skill) and by making your existing wealth earn you more wealth.

If you're trying to nickle-and-dime your way to an early retirement, you're probably just going to be miserable drinking bad coffee and watching old reruns, while you continue to not retire.
