Well, if you get that feeling then go with it. Maybe have a semi adventure. When I was younger and single, if I got the feeling I wasn't enjoying myself I used to go for walks and listen to my music. I'd pick my favorite stuff, make some playlists, pack a backpack and trekk through my city. Often alone, but occasionally with a friend. It made my body feel great, and those are some of my favorite memories. You never know what you'll see, or what could happen.
