Method not to sin

So as a Christian we all try not to sin and watch at porn is a big sin. I've heard from a method called H.A.L.T. which means something similar to stop in German. Its meaning are the situations when we sin. We mostly sin when we are weak like when we are Hungry, Angry, Lazy or Tired (H.A.L.T.). If you are close to commit a sin just take a breath and repeat "Halt" in your mind as long as you feel tempted. If you feel better, congrats you won, if not go read your Bible or pray. Gos bless you all
