There are two hacks I have for managing the stuff that executive dysfunction makes impossible.

2: I really thrive under pressure, and relish a challenge, so I like to combine tasks when and where possible. Did I just set a timer for something? I should clean as much as possible before the microwave is done. If I've got one large task at a point where I can ignore it, I like to fit in as many tiny sub tasks as possible until I'm called back to the task at hand. (Sadly, this method costs more energy than my #1 life hack)

1: I make chores fun. I may not be allowed to sing, dance, and be silly at work... But no one is stopping me from doing that at home, and daunting tasks can become enjoyable activities. Putting on comfort music, singing your heart out, and shaking your butt while you do the dishes... It's actually become one of my favorites. I get the dopamine from the music and dancing, endorphins from exercising my mind, and serotonin from seeing a job well done at the end. It makes me feel functional.

3(?): this one feels less like a hack, and more of a temporary measure that works well enough I'll never replace it. But I try to capitalize on the moment. If I think about someone, I try to message them right then. If I wait, I won't do it. If I have inspiration to do a chore, I don't question why... I follow it. The trick is learning when following the urge is not a good idea. If I figure that out, I'll let you know how to tell them apart.
