What next?

Well, I've been wanting to do it for quite some time now. And I finally built up the courage to do it. I quit my job...! It doesn't feel like I've done it and I'm kind of scared of what I've done. Why? Because I have NO PLAN whatsoever, but at the same time I need to keep telling myself that I need something new and I need to be happier. What do I do now though?
