Satan doesn't have to get you to become a mass murderer to defeat you. In fact, all he has to do is get you to give up, and that's partially why Jesus " was telling them a parable to show that at all times they ought to pray and not to lose heart." (Luke 18:1)

Is the world beating you down? Does Satan want to get you to grow weary of doing good and just throw in the towel? Don't let him! I may be a surly curmudgeon myself, but I'm always willing to lend some of my stubbornness to help someone overcome, and lots of people are even better at that than me!  Pick a prayer partner, too. It's a fantastic thing to have.
