You fellows are familiar with Murphy's law. Let's place an addendum and I'll give the credit to Wawak. My wife does professional sewing and buys her commercial grade thread from this company. In her last shipment was this card that says:
Measure twice.
Cut once.
Curse.
Repeat.
This could apply to metal workers, wood workers, etc.
