I'm not nervous, I suppose "apprehensive" is better term.
The "no-boot" scenario is always a dissappointment but since "learning" is one of my favorite pastimes, I know I'm in for an enjoyable, but maybe frustrating, time.
I've made it a premise in life to turn every situation into a positive learning situation. This includes being arrested, incarcerated, working with dick-weeds for 30yrs, and your everyday grocery shopping.
I really enjoy getting a few friends together, drinking some beer, smoking some left-handed cigs, listening to music, and doing a build.
I suppose it all depends on your outlook on life.
