Check my name. Go to the library. Netflix is good, but you don't necessarily need it if your library is as good as my local one. You're already paying for it in taxes presumably, so go get some books, magazines, movies, CDs and/or video games and enjoy that. Once you check out a handful of items or use other services, you've more than recouped your annual "loss" from taxation. Most libraries also carry ebooks and other electronic media. For example, my library has a digital magazine platform, streaming video service and a music service called Freegal where you can download and keep 3 songs per week.
I workout regularly at home. There are lots of free workout videos on YouTube and Vimeo. I've even found full P90X workouts online.
I play lots of video games cheaply. I buy games waaaay after they come out and are in used/discount bins or sometimes just swap with friends. There are lots of free games on smartphones nowadays like Solitaire or Hearts that are free ways to kill time.
I also enjoy writing sometimes. It's fun even if it is dorky or emo sounding. Also, buy yourself an instrument off Craigslist. Whatever your fancy, you can teach yourself simple songs at home at no charge. I learned some basic acoustic guitar and it's fun to do every now and then.
