Have you ever felt that you don’t know how you spent your money? I mean that extra money that you have after your living expenses and savings for a rainy day. where does it go?. In my case I have a vague notion: a book that I saw in the bookstore, a coffee when I came across the cafeshop, the beers I drank with one of my friends and so on. I’ve come to some ideas about figuring out how this money is used month by month. I’ve created a google sheet in order to have a detailed register of my spendings, and it’s working. it has been easy to have this register, cause you can make an entry form your phone every time you spend some bucks, in that way I can know exactly every spending and give the opportunity to be aware of some buyings that I’m not on top of or I overlook.
