How do universalists avoid tempation?

I've been having a rough week, wondering what it would be like to give up Catholicism and be a Unitarian. But I was wondering, how have universalist leaders taught their adherents to avoid temptation without the constant threat of Hell? As a Catholic I really hate sinning because: 1. It makes me unhappy or sort of badly happy. 2. It chops me off from grace in some way that I can't quantify. 3. I have to go to confession and I REALLY don't want to do that. So, without the Sacraments and the threat of Hell, what do Universalists do to stay on the straight and narrow?
