If you want to make the world a better place, scrap every right you have ever heard of. Scrap human rights. Scrap right to free speech. Scrap any right based on nationality, color of the skin, gender, or any other superficial stamp. Because almost every right only leads to a sense of entitlement.
If you want to make the world a better place, start speaking of human responsibility. It's simple because, instead of a million rights to choose from, there's only one responsibility: the responsibility as a human to respect and help others; the humans, the animals, the nature. Because from all the creatures on the Earth, the humans are the most capable of surpassing their basic instincts. Don't judge actions of others based on rights of yours or others, judge yourself and others equally, and only for the lack of responsibility.
If you want to make the world a better place, scrap the borders, and respect the culture and customs of all the people. When the people and cultures spread and mix, scrap your fears of them violating your rights. Scrap the dream of becoming rich. Instead, dream of happiness, you don't need to be rich to be happy. If you're in trouble, don't be ashamed to call for help. It is part of the human responsibility to help those in trouble, but not to make you feel happy. That is an attitude choice, which only you can make.
Seek freedom from fears. Seek freedom from the power of money. And most of all, seek happiness. Just don't make any of it your right over your responsibility as a human.
