Pre-FIRE, I did it monthly, wrote it on a brightly colored post-it and slapped it on the wall of my home office. Post-FIRE, I rarely check. Looking at our main statement on line and checking our primary house's value occasionally is about it, because having ENOUGH! and knowing it, even when the stock market is down, and our current flip project is taking longer than expected, is a joyful feeling. Hell since DH pays the bills now, I hardly even check the bank balances. There is incredible freedom in knowing your habits are so ingrained, and your stache is so bounteous, that there's always enough there. This feeling far surpasses the purported joy of paying off a cheap, affordable mortgage any day. Every day, in fact.
About those notes on the wall: very few people ever saw the inside of my home office. One who did was the guy who painted my house. In an odd twist of fate, we got married nearly 12 years later, which was a shock to both of us. We're still happily surprised, six years on. The good news is that his NW was about the same as mine by the time we wed, and though he's not a mustachian, he's a naturally frugal (but not cheap) dude. He never said a word at the time, but later told me he had seen my notes and was impressed at my dilligence.
