Try to learn to breathe deeply, really to taste food when you eat, and when you sleep, really to sleep. Try as much as possible to be wholly alive with all your might, and when you laugh, laugh like hell. And when you get angry, get good and angry. Try to be alive. You will be dead soon enough.
If you want to change the world, first try to improve and bring about change within yourself. That will help change your family. From there it just gets bigger and bigger. Everything we do has some effect, some impact.
This is the first lesson to learn: be determined not to curse anything outside, not to lay the blame upon anyone outside, but stand up, lay the blame on yourself. You will find that is always true. Get hold of yourself.
