I reached FI a couple of years ago, and my COL is so low I don't have to pay much attention. I've set up my checking account to accept ebills. I get an email notification when an ebill arrives, it takes about 2 minutes for me to log into my checking account and send a payment. Since I am retiring in just a few weeks I logged into my account to check balances and possibly move things around. Between my direct deposit paycheck, annual bonus/raise, and tax returns from Federal and state my checking account balance was outrageous. Seriously I could pay off my mortgage and have money left over. I did move it from checking into savings but I really need to find a savings account that pays better interest or invest that pile of money.
MPP = once you become established in a Mustachian lifestyle money starts to pile up like old magazines if you don't pay attention. It takes some diligence to keep those little green employees productive.
