On another site I saw a bit about how, “The customer is always right”, is just plain wrong. I had been taught that as well and soon found out just how wrong it truly was.
Remembering that got me thinking about other things people assured me were truisms, but were not.
When soldering, “The bigger the blob, the better the job”.
“What you don’t know, can’t hurt you.” This only applies to someone saying something negative about you.
Someone demanding to be updated with, “Only good news.”, is unrealistic.
“Super glue will fix anything.”
“WD40 will lubricate everything.”
“Blue LocTite will temporarily secure any fastener; while still allowing that fastener to be easily removed.”
“Use a lot of thermal compound.”
You can’t have a bad day, “If you don’t let it be one”.
“If you don’t worry, there will be nothing to worry about”.
“You can control your emotions.” is incorrect. However, you can try to control your reactions.
Lastly, the “five second rule” for food dropped on the floor.
What incorrect things were you taught?
