- If something's wrong, something's wrong. This is a conclusion reached jointly by my closest friend Dr. Captain Right Reverend Frank Hanna (Frank is second from right in this photo from 2000 of the Northern Arizona University Department of Geography and Public Planning), may he rest in peace. It came to us during flying together but has wide applicability in business, at home, and elsewhere. For example, I'm flying at 11,000 feet density altitude, power is at 27" manifold pressure and 2,400 r.p.m. I usually get 142 knots indicated airspeed in this situation, today it's 132. "Huh, oh well, la de da." 10 minutes later: "Oh $*)^%*, I forgot to put the flaps up." If something's wrong, something's wrong.
- If it did, then it can. Frank was a professor of geology and took students on field trips, sometimes to map geological features. Students would look at, measure, and map some feature, scrunch their brow and say "but can it do that"? Answer: If it did, then it can.
- If they are, then they do. I got my start in the business I'm now in via performing inspection of various facets of building construction. I'd see some very shady things apparently involving various quid pro quos (quids pro quo?) between contractors and construction managers (who ostensibly represent the interests of the owner of the development). A newer inspector would say "Do they really do that"? If they are, then they do.
- Everything is dramatically more difficult and complex than you thought it would be, even when you allow for things being dramatically more difficult and complex than you thought they would be. This applies to everything from installing drywall or toilets to welding to applying conservation of momentum to a dynamics problem. Self explanatory.
