A man walked all this way. To find nothing except pain. He kept walking to become one with his surroundings. And learned how to be happy here.
Happy Here is that form acceptance I think most adults have to go through if they want to be more content. In life you will suffer, so if there is no comparison to a life without suffering, then can we really call it that? The important thing is not to fight off those thoughts of disgust, hatred, or melancholy, but to instead see them as conditions of existence. If you can understand that "it's all terrible" and accept it, then you'll learn to approach hardship like everything else.
