I work a job where I deal with a lot of deadlines. I've never missed one, but my priority schedule works on a FAFO basis. We FA until it comes to being almost time to FO, and we really don't want to FO.
So then I tear ass through my tasks until I've done two weeks worth of work in an afternoon lol
That's how I pack for trips. My wife thinks lists are the way to go. I keep telling her if she just waits until the last minute I'll do it all myself in record time. Probably get everything, too.
I used to do tasks out of spite. I hated myself so I forced myself to do things to spite myself. So if you're looking for a change in unhealthy coping stratagies then theres that.
