I only have two pieces of advice here.
1. Don’t resign while naked.
2. Don’t resign by using firearms.
Otherwise, whatever you do is probably cool. A friend of mine danced on his desk in the law office while cutting his tie into small pieces. The second time I quit the day job—the time I quit for real—I went home and had a bonfire in my back yard in which I burned my uniforms. (There are times when living in the country is a wonderful thing. That wouldn’t have been nearly as satisfying in a fireplace.) It was great. And my life has been an adventure ever since.
Best of luck to you, wild and woolly fellow writer. This is what I have to offer that got me out of the day job—what I did as well as what I should have done. I hope you make it, too. It’s worth every bit of struggle, and it’s worth it every single day.
