Congrats, I did the same a few years back. I quit with nothing looked up because I had enough savings to make it for a few months without worrying too much.

I took that time to really relax and try out a whole lot of different hobbies before I got a job as a contractor to a different team at my old company.

All the best to you. Enjoy this opportunity you've made for yourself and make the most of it. Explore and figure out where you really want to go in your life.
