This is great keep going.

I find mis-en-place is a great optimization, especially if you have kids.

For hot water, I have a 2L thermos which I keep filled with boiling water to make hot drinks, with a quick reboil if necessary, and also to use as cooking water. I think there are plumbed in versions of this which would be even better.

Bread-making - I just use a bread machine to make day-to-day bread (specials hand baked etc on weekends sometimes.) For the daily, I pre-measure ingredients (both wet and dry) for 10+ loaves, individually packaged (kids are a great production line again). The to make the bread, just throw in the packets and press the buttons...

No doubt most people already do this, but for some reason my wife can't get it .. keep everything in the same place all the time. It really wastes time and 'stressergy' to have to hunt for the measuring spoons or the molasses or whatever because they were put back in a different place.

I'm sure commercial chefs could add a huge list of tricks that are still applicable at home to this.
