Ask HN: What is the most ingenious yet simple life hack you have used?

This isn't profound, and maybe crazy, but owning only one kind of sock for everyday use so there is no sorting on wash day.

For a while I didn't even roll up pairs and had a drawer with loose socks and knew that grabbing any two was good enough.

Also, when you get a hole in one, the other isn't orphaned like with unique pairs; it just goes back into the pool.

Keep some nice dress socks for days that require formal dress, but but for everything else, just one type.
