Read the book several times, recommend it all of the time, and LOVED it. It helped me so much with my son and myself.
Some things that come to my mind:
Stubborn=headstrong
Argues=always has an answer
Picky=knows what he wants
Wild=likes to have A LOT of fun

Another thing that has worked so well is sticking to what I say, not backing down on the consequences. It's OK to let them know you are not happy with their decision to not listen to you. They are still a good kid, but they need to work on making better decisions. I think that was key for me, to let him know he's a great, funny kid, but at times needs to think things through a little better. So we talk about it when the time-out is over.
I have family members too who tell me to spank him when he throws a tantrum. It breaks my heart to think that because your child has reached a breaking point or too many transitions or just plain frustrated they think it's OK to hit them for it. What the child needs is comforting and some time to wind down, a nap, food, the tags cut out of the shirts(I've had to cut all of the tags out), etc. Not to brag, but he is WAY better behaved than some of the kids in my family who have been spanked and the family has recognised that now.
