One of my favorite legal quotes is from Elihu Root, a famous Wall Street lawyer a hundred years ago or so. He said "About half of a decent lawyer's practice is telling prospective clients that they are damn fools and should stop."

Bonus quote from the same source for litigation lawyers:
Under Rule 11, eventually, after expensive litigation, a party might convince a judge to sanction a bully's lawyer for filing a frivolous lawsuit. Rule 11 awards are extremely rare, kind of like sightings of Bigfoot.
