Whether it be to do your job, get your schoolwork done, clean your house, work on your creative passion, etc.
Bonus points if you’re someone without reasonable self-control so saying something like “I can only have a cookie after I do this/while I do this” doesn’t work for you and you’re just going to eat the cookie and not do it.
I often just fail until it gets embarrassingly or super inconveniently bad. My only strategy that was ever even a little helpful was breaking the task into tiny micro 5 minute tasks and writing them all down, and doing a few of those at a time. I had adhd though, and am hoping medication will help with that (so far it has a bit).
