Not new, but my biggest one is physically placing things I need to remember in the path of my daily routine. Like if I need to remember to bring my laptop to work, I might put my computer mouse in my shoe.

Another one is moving things in stages. If I'm cleaning my living room and something needs to go upstairs, I'll just leave it on the stairs for the next time I go up. Otherwise I'm likely to get distracted when I get up there and forget to continue cleaning downstairs.

I also try to have multiples of things that I use in multiple rooms or places. Like a small trashcan in all my rooms so I don't have to go somewhere else to throw it away. It minimizes distractions and helps me stay focused on the current task.
