I have trouble sticking to routines, so I've been trying to make lists to keep focused.
It doesn't always work though.
At the moment I've got a word document open on the computer with a list of chores to get done today. Then I can just pick something off the list (doesn't have to be in order, because there are things I'm trying to avoid ). Change font to red for the one I'm supposed to focus on. Change it to green when it's done. I like being able to see that I've achieved things. If things don't get done then I just delete the list and make a new one next time. I try to keep it realistic, but I rarely finish everything.
I tried getting a notebook with pages for different things (things to do today, uni stuff, house cleaning, bills to pay, etc). Anything that needed doing got put on a post-it and stuck to the right page. That way I could update or prioritise lists easily. It doesn't really work because I don't check it often enough, but it's good for longer term goals.
Keeping things in my head doesn't work. My brain gets full and I can't focus.
