One thing that will derail me in the kitchen faster than anything is having too much going on at once. I don't fix things that require boiling this while sauteing that and mixing some third thing for an exact amount of time -- I know I'll lose track, mess up something, and end up a wreck by the time it's over.
I also keep meals simple, opting for bagged salad or raw veggies with dip instead of adding one more thing to cook.
