These probably aren't the best ones out there, just what came to mind easily:

• For people who take a few different medications, those weekly pill box things - it takes less attention to do it all at once when non-groggy.

• Keeping one's workspace clean and organized might be an example; a lot of people say they can pay attention more easily when things are clean.

• Keep bicycle tires well pumped - makes you go a lot faster. (Also, having the correct kind of tires. Mountain bike tires are slow on pavement.)

• Set up the computer/browser to automatically open the tabs/programs you use the most. (I know some people who do this on their work computers.)

• "no 'poo" hair washing makes hair less oily so you need to wash it less often. Also cheaper. (baking soda + vinegar is the usual method.)

• buying two weeks' worth of groceries at once so you don't have to shop as often

• Dvorac and other alternative keyboard layouts

• email inbox automation things (I've not used any, but people seem to like them)
