The biggest challenge with the All-Cash Diet, of course, is to know the right amount of cash to pull out of the bank each week. Many worry that we will spend too freely if we carry around more cash than usual. But I'm convinced that's a psychological barrier that prevents us from doing what's best for ourselves.
Try the All-Cash Diet for a month and see how it goes. There's no money-back-guarantee, but my bet is you will find more money in the bank.
