Do you get nervous?

YES. Fired up a fresh engine today. Only my second build. First one fired right off with 1 small coolant leak. This engine has fought me the whole build. Today did not go smoothly but it's running but can drive yet. Now the punch list has about 5 items the worst being another coolant leak from the cam cover bolt behind the water pump lower hose inlet. It's gotta come off. ARGH!!
Im going to be nervous for the first month on this one.
