It's not lame to stay in every Friday night.
Often, I look down on myself for declining almost every invitation to hang out with friends, and then I feel even worse when I pop on Snapchat and watch story after story of parties and blurry videos taken with flash of people goofing off at 2am. I get it, FOMO (or the Fear of Missing Out) is real and lives in all of us, and it often seems as if people stay home on the weekends by necessity rather than desire. During moments like this, don't feel pressured to need to go out with friends all the time in order to keep them, because there'll be plenty more opportunities in the future. More laid-back gatherings at home with pizza, board games, and movies may suit your fancy a bit more, or even a catch up with friends over lunch during the day. As introverts, we need time alone to recharge, whereas extroverts feed off the energy of a social buzz. Don't feel like you're missing out when you're snuggled up in bed at 11pm, after all, we're all doing what we gotta do to recharge.
