I'm guessing a lot of us have issues with this. How do you handle them?
I've tried writing to-do lists, which I love doing (think of all the possibilities of all the different things I could get done in a day!) but the day always seems to slip away without me having done half the stuff on the list. I've tried writing detailed lists, with every specific task I need to do in the order I should do it, and more general lists, with "Spend x hours working on homework, x hours working on cleaning," etc. Doesn't seem to work for me.
If I need to clean or organize (which I always need to do), I find some movie or TV marathon to watch and make an event of it. Lost marathon and clean out the closet day, Humphrey Bogart movie and clean my room day, play star wars drinking game while attempting to sort and fold laundry night, etc. But when it comes to tasks requiring me to sit still and pay a lot of close attention, like writing or job-searching and applying, I'm hopeless.
Right now I'm telling myself that if I spend the entire weekend (including tonight) finishing an application and applying to every job I can find in my region that I might remotely qualify for, that I can spend Monday having lunch, seeing Shutter Island, and doing whatever I want without worrying about all the things I need to get done. Hopefully this works but I'm curious about everyone else's strategies.
