"Do this, this and this."
"Okay. And what do I do if that doesn't work."
"Just do it. It will work."
"But what if it doesn't?"
"JUST DO IT. If it doesn't work, then we'll have to take a closer look at it, but there's no sense wasting a bunch of time on it if there's a 99% chance that this will fix the problem."
"Make the change. If it doesn't work, call me back and I'll come up with something else."
Don't make me reach through the phone and rip out your soul.
