Single and find yourself with a lot of free time? Instead of filling it up with netflix binges (which is fine) here are some ideas I've found myself doing that could work for you as well (When I'm not vegitating).
Get physically active!
I'm an avid climber + and yogi (brogi?) which would have never happened if I didn't look for something to patch up my time in the single life. I've made a lot of good friends and genuinely enjoy any time I have to practice either one. But you can try running, dancing, hiking, swimming, weight lifting, frisbee, soccer etc. all which are relatively inexpensive. The community behind any activity is also strong so you'll make good friends off something you know you share an interest in.
Meetup is great for this and facebook groups.
Pick up a skill!
Level yourself up! Have you had any thought of picking up an instrument, learning how to cook, sew, change car breaks, etc? Well enjoy that free time and practice! In a way it'll give you a passion which is important throughout any stage of your life. Guys and gals, if you don't know how to cook and are single get on that. You'll love yourself for it.
