Give positive reinforcement whenever possible. Be a stable point of reference. Consistent, fair treatment and logical consequences provide the best framework for getting along. When no built-in consequence to an action exists, devise one that is logical and fair. Don't be afraid to admit that you, as a parent, were wrong and that you're sorry.
Mutual respect is a goal worth striving for.
Recognize your own limits. Drug and alcohol abuse or self-destructive behavior can be beyond your ability to help. Seek professional help as soon as you need it.
