Hookers & Blow will rip you out of a ho-hum life. /s
Actually, get rid of your TV. Don't sit and watch stuff onscreen. Chuck Netflix, Hulu, etc in the trash heap. Why? Because it feeds you ideas of some exciting life while making you feel ho-hum about the one you've got. In all that screen time, you could be walking a dog, learning to foxtrot or roll a kayak, building a garden, having wild sex, practicing the accordion, retraining for a new career.
Point is, if your free time is boring now, having more of it after you've shed the dreaded job isn't going to bring endless thrills.
More importantly, find a way to be of service. Do something for someone or something else. Make a commitment to doing it regularly and then do it. I don't mean give money, I'm talking about giving time. For 9 years, I volunteered 4 hours per week with an arts related non profit. In addition to a fun social activity, it conferred no small amount of ego stroking celebrity status. These days, I take a dog to visit a dementia care ward. Best thing ever. I've done some exciting things in life, but nothing compares to the pure joy of bringing the dog to visit folks who barely remember that they just ate. The old guys pet the dog and reminisce about Sparky or Major or Duke who was their constant companion three quarters of a century ago. The dog wags his tail and patiently accepts pets and hugs from all the old ladies.
I don't mind if you copy my thing, there are plenty of dogs and old folks to go around. But you will need to find the thing that gives your life meaning in order to vanquish all the ho-hum out of your life. Watching TV and regularly scanning social media can be impediments to finding your thing.
