Life has unexpected turns, truly anything can happen. It is not over until you can be happy.
There is not a guideline for happiness that you can find online. You must find it in your world. A world perceived and made by you, a world that is hidden.
The facade must be taken down, or you will lose yourself in a world of standards. You can not find happiness in someone's world, you cannot find it in science or religion.
But the world you plan, construct, and live in.
This world will have happiness, peace, and above all Love that will never die.
