What makes your job so cool?

My answer is simple- my job is so cool because it's something that I love to do, where I can be creative, and I can make people happy.
S/F

I conduct health/sanitation inspections and write MFRs for said inspections, and I even manage to upset Chains of Command with my MFRs (I made a whole bunch of Field Grade Officers mad in Iraq, once) when I report my findings with pictures of the nastiness I find. Then I go have lunch. People can argue a memo all they want. They can't argue a memo that has pictures included.

I Get PAID to ride Motorcycles, Every new model in three brands leading test rides. R&D of the model and / or tire testing. Riding and teaching others to ride every week. Industry Media days. Customers that drop off a check or pile of cash and say Build it....Others that have a garage full of bikes and bring them on a rotating basis so every month I have a different bike to work on, ride and enjoy till next month. It ain't jumping from a fixed wing at 30K AGL but it aint sitting behind a desk either.
