Do you want to go out? I mean, I consider myself an introvert, so I always prefer staying at home, so I only get out when I want get out or when I have to. In the past, many family members always told me to get out more, because apparently staying at home is not good and I just disagree, I like being at my house places and I'm pretty happy there.
But of course, if it's affecting your health, like lack of exercising, eating junk food everyday, then I think it would be safe to change a little.
Nevertheless, I do go to the gym almost everyday and to supermarkets, although that doesn't mean I like going out and be in really crowded places.
So yeah, maybe start going to the gym? It motivates me to go out everyday.
