The Most Wasteful Money Habits
Excess utility usage
Letting the AC stay on at a mild temperature for days, when opening a window would have been fine. Leaving the living room light on all night to scare off burglars, when you have motion sensor lights outside. Letting the water run while you brush your teeth or while you wait for the shower to heat up. Work on that water heater: your shower shouldn’t take five minutes to heat up.
