I never kept track of expenses until my DH retired, & now just to keep us on track, we log everything. No more sneaking it in the house LOL Kidding really, he has always been good about that and always gave me the line, "You know how much money we have" Prior to retirement however, I did tend to stock up though so don't have to buy nearly as much as when I started out. I have PLENTY to keep me busy for a couple lifetimes : )
