Complete one of your four weekly lifts from Les' training guide, or if you've already hit four this week, do 30 minutes of any physical activity — walk, run, bike, whatever gets you moving.
Tonight, however your evening looks, make sure your wife knows she is seen. Cook if you can, order her favorite if you can't, pick something up on the way home if that's all there is time for. The meal isn't the point—the intention behind it is. Pour her a drink, sit down together, and tell your family before you eat that you're grateful for them. Mean every word of it.
