We need each other
In this life, we need each other to survive the harsh environment of the universe. No on can do it alone it's really annoying and discouraging to see some people exhibiting selfishness and only care about themselves. The world is created in such a way that we depend on each other to survive. No one is an island. That's why family and friends exist.
We need to give to each other when it's required of us. Love and unity should be our core value, with them the world will be a better place. Never discriminate against anyone because no one is complete. We humans were created to dominate and take care of the world. We can only achieve it through unity, cooperation and relying on each others ability.
No human is perfect, our gifts in life differs and we all need these different gifts. Since we need each to survive and live a better life then we should leverage on it. No one is complete, we should complement each other and make the world a better place.
