1. Splitting the housework 50/50. This is often considered the "fairest" way to split the chores, whether it's washing the dishes or walking the dog. But aiming for 50/50 means you're constantly keeping score, making sure that neither of you is getting the short end of the stick, and bickering every time you think you are. Spend too much time fixating on fairness today, and you risk not making it to the long run when things often balance out.

It's better to use a system similar to what economists call "comparative advantage," where each of you is responsible for what you're best at, relative to other tasks. You might handle all the bills, grocery shopping, and laundry, while your spouse sweeps and mops and fixes things when they break. Some weeks, you'll end up doing more, other times it might be 75/25 in his favor—but you don't keep track because if your husband handled the grocery shopping, you might end up with a pantry full of Tostitos.
