Jury Duty Tomorrow - Oh Sht

Tomorrow I have jury duty. For the first time in my life, I will step into a court room. While I've been called to jury duty in the past, it has always been nullified by outside circumstances (e.g. I had moved, or was out of the country, etc.). Having the right, as a fellow citizen, to judge another citizen rather than letting some tyrannical structure or entity do this isn't lost on me. However, being summoned under the penalty of violating the law does feel like an imposition on my life and it certainly will cost me more to participate in the jury than if I spent my time doing other work. Further, I'm nervous about the duration of the trial I would be part of if selected. A 6 month event, while low in odds of happening, would hurt my career. This will be interesting to say the least.
