Initially, I thought it would depend on what day I was stuck in. But after a number of loops I think that would become redundant (if stuck in a true, endless loop). After testing the boundaries and satisfying a number of indulgences; I'd alternate between skateboarding, music and coaxing my wife in to ditching work so we can hang out.
Furthermore: I think, given long enough, with the changing perception of time; eventually I'd acquiesce to a form of auto-pilot. I'd just live out the day as intended for large portions of my unlimited time, deviating as and when I can be bothered.
