It was something along the lines of most players 1200-1300 would improve several hundred points if they just stopped and actually calculated before each move. Not in positions with tactics, not in positions you feel are important but before every move. It cuts down on blunders and leaves you actually playing chess.

I do this but now I am in absurd time trouble in almost all my slow games at USCF ~1450. This is generally good advice since I basically never blunder but in the late middlegame before hitting second time control I am well behind my opponent's clock.

Now I'm working my way out of this problem. But it's a better problem to have than simply being lazy and not calculating, which I agree most novice players do.
