How And How Much Money

Sometimes I wonder how much money it takes, and precisely how one goes about, dealing with all of the daily bullshit. I mean not having to deal with the cable company, or not having to worry about calling your damn credit card company when you're planning to do some international travel. Yeah, I get that you hire accountants and assistants and such to take care of a lot of that stuff, and the Amex Plutonium Card probably doesn't cut you off as soon as you try to charge a coffee at the Heathrow Starbucks, but some things seem to inevitably require personal participation. How much $ do you need to realistically not ever have to deal with any of it? What Would Mittens Do?
