takeoff checklist
Many years ago, in the military, we joked about this checklist...
--Watch
--Wallet
--Testicles
--Spectacles...
...Cleared for takeoff.
--I have not carried a watch for 10+ years, so we can scratch that one.
--Wallet...yep, haven't figured out a way to walk out the door without it.
--Yeah, they've been disconnected from the pipeline, but they are along for the ride.
--After Lasik about 12 years ago, these are also surplus.
So the modern checklist is:
--wallet
--keys
--folding pocket knife
--handgun
and, usually, a spare magazine or speed loader.
Keep it simple, work to consciously develop good habit patterns, and you will do just fine.
