Fill up your social calendar

When it's cold and dark outside, it's easy to settle for a night of Netflix and take-out, but isolation won't work in your favor. Resist the urge to stay in and make an extra effort to fill up your social calendar. Go out with friends, see a show, or pick up a new hobby. Finally, a good reason to justify going out to dinner every night.
