This is another one that must be included in the long-term: being adaptive. Not only to your child but to the times. Be aware and be up to date with modern news. If your child breaks the rules, try to understand before judging them (while also giving warmth). Be sympathetic and understanding.
It is more important than ever since modern technology has caused more distress among the youth. By being assertive and adaptive, you would teach your children to both stand firm and adapt. Teach them that they should adapt to newer situations while holding their ground if they are ever told to adapt out of their morals and ethics. Adapt to both social and academic pressures imposed by gadgets, while also asserting their own beliefs and order.
One of the important key... "try to understand before judging"...
