Passing or failing doesn't mean a whole lot for my life, I don't know yet if I'm even ready to take the job if they offer it. I'm sorta of interested in it to find out how good I am at this point. I don't think I'll pass, which is scary. I'll have supreme confidence when I'm there because my skills and intelligence are more than ample but my life experiences not so much so.
I know I'm actively betting against myself to keep it from hurting as much if i don't pass. I'll be OK, I can prove myself in other ways and will rather soon, but not passing will hurt.
Fortunately, I'm prepared to be at my best, calm, relaxed, friendly, and smart (though i will have to suppress smart-alec tendencies) I'm a natural but it may not be my time yet and i just don't have time to completely prepare the strong points of my life story. but I will be ok, even if I fail.
Course, if i pass, i'll be insufferable, fair warning for any that would wish me luck ;p
