I have learned so many things from my difficult child, among them:
1) Attend to the behaviour, not the words. difficult child will be protesting vigorously with his mouth that he WON'T do such and such, while his feet and hands are doing exactly what I asked. As long as I say nothing further and let him get on with it, he gets it done. It's too easy to focus on the verbal output. Sometimes we need to look instead of listening.
2) Be explicit. With instructions, emotions, heck...with EVERYTHING. My difficult child has face blindness co-morbid with his aspergers. I have a flat affect because of my aspergers. His trying to read my face is pretty-much impossible. So I tell him. "I'm very happy with you right now." Or, "You're making me angry." Or whatever.
3) Say what you DO want, not what you DON'T want. difficult child (heck, ALL the children) are masters at selective hearing. If the only thing they hear is "socks in the hamper", when I've said "Don't put your socks in the hamper because I've trapped the pet hamster in there", then trouble will ensue. So, instead I say "Put your socks in the laundry basket" or whatever it is.
4) Save "No" for special occasions. In other words, only use it when it's essential.
5) Even in the most horrible moment ever, difficult child quirky humour can make everyone lose it with hysterical laughter. Which is often the best medicine for the horrible moment underway.
6) A weakness can be a strength when applied properly. difficult child's bossiness and grandiosity makes him great in a crisis, when other people are running around in a panic. He keeps a cool head, tells everyone what they should be doing, gets them calm, reassures them. The only fly in this ointment is that sometimes his judgement is off, so he sends people down the wrong path. We're working on that part.
There's so much more, but those are the first few things that come to mind.
Great thread Malika.
