Yeah, I had to break myself of the habit of leaving the water running. When I was younger and less patient, I would soap and rinse each item in sequence, so that I got the sense that I was making progress. But as I got older, I switched to batching the soaping and rinsing as it is more efficient that way.

Also, an additional difference between handwashing and using a dishwasher is the environmental impact of the manufacturing of the dishwasher, if the main concern is the environment. If the main reason is reducing work, then the dishwasher comes out ahead.
