I'm a big believer in tradition, rituals and schedules for productivity. For example, working at the same desk, at the same time of day, with your favorite playlist going on in the background.
But, sometimes those rituals can get stale and this is when it's time for a change. Moving the furniture, or location is great! Using new tools, or even listening to new music. Anything that gives you a breath of fresh air and stirs up the routine can bring excitement into approaching your work again.
