Sounds like it's time you started your own company. Well, at least consider it seriously before imagining yourself employed in some other place. Anyway, it's probably better to wait before you start going to interviews and such, as you might be too sore because of what just happened and it might show.

Anyway, if you think being fired is real sh!t, you're right only if you're convinced you could only work always having somebody telling you what to do -- i.e. employee.
