These are new ones that I've been learning in Gottman-style couples' therapy - some of them I'm not so great at putting into practice yet!
1) Find something you can take responsibility for. Not in a grudging way, not in a self-punishing way, just with some generosity of heart. None of us is perfect, we're all stuffing up all over the place. Find something to own.
2) Find something to affirm in the other's point of view. Even if you don't agree with the whole lot, find something.
3) Make time to say the positive stuff, about the other person, your relationship, what you're learning and what you're hoping for or committed to. If you're mad you might not remember the positive stuff - but think - there will be something. Share it.
4) Keep your sense of humour. See if you can find the gentle-funny side of the situation, including yourself and your flaws and foibles.
Hope that helps a bit - I gotta work on these too. I'll post the first ones I wrote below.
