Risks are a blessing when taken seriously. Have your own opinions, but make opinions wisely. Never stop learning, no matter what the obstacles. Have compassion for your fellow man, never judge someone without putting yourself in their place first. No matter how close they are, as they get older their beliefs change, and you drift apart.
Nothing is forever, so accept letting go of things and people.
If she's slipping, find help for her. Don't watch TV, it's full of shit. Always help those who need it, friend or foe. Learn all you can about the world and travel. Make school part of your life.
