Watch your favorite television show? Do it.
Brush your teeth? Do it.
Read new A. Lee Martinez novel? Do. it.
There's a fine line between being able to just pick up and do something, and being on autopilot and doing them because it's a habit. For the most part your day is full of repetition, mindless droning about at work, or school, driving the same roads at the same time and likely eating about the same foods on the same days at the same places. Even when you attempt to try a "new place" you'll likely escape back to a safe dish that is generally good at other places.
Well my habit is to eat nachos at the little mexican place across the street, and not just there. At least once but not limited to two or three times a week I have to have mexican food in my stomach. Most of all, I desire nachos, I want them and I believe they want me just as badly. That warm gooey cheese just laying on top a bed of freshly baked chips like a evil swimsuit model beckoning me to draw near. Most of the time I can shrug with a sly grin and say, "Maybe later babe, I gott a play hard to get", but eventually I fall victim to the siren's song.
