What do you like doing? You could go hiking, biking, walking in the city, get a camera to take nature pictures to enjoy some solitude... or go to the club to dance or people watch, shop for friends and family as the holidays approach, volunteer at your local soup kitchen. Run a marathon, the practice required will occupy a lot of your free time.
There is so much to do.
WHAT I CANT DO THIS..boring
I like my martial arts class, but that's just me.
Maybe try to join some meetup.com groups?
Netflix. But it would be better to get out and see people. Maybe you could volunteer or go on a nature hike or read the paper for groups that meet locally.
