When you know that a good chunk of your next paycheck is going to buy new bottling equipment, but its a nice day, and you have to force yourself not to stop at LHBS and buy another carboy and beer kit.
When you deliver dairy products, and one of your stores is replacing refrigeration equipment so you load the old stuff on to your semi with no idea how you will get it off the trailer, get it home, or get it in your basement, but you take it anyway.
When you drill the hole in your keggle a bit to high for the thermowell, and you just say oh well I will just have to only do ten gallon batches, oh well I have two other kegs anyway, or oh well guess this will just have to be the HLT.
