Maybe the guy just barely started the book.
When I think of friction tape I'm almost always transported back in memory to that time in WWII when my best pal Joey and I were hunkered down in a fox hole and that dog with one leg delivered the message from General MacArthur about Joey's girlfriend, how she was touring with the USO and her plane went down and Joey was afraid he'd never see her again. Call me shallow, but when Joey was reading the letter all I could think about was how much I hated K-rations.
I don't know why friction tapes reminds of that. Maybe because back then people were less safety conscious than they are now.
I sure hope that guy finishes his book soon.
The habits of highly effective people . . . eh.
