I do not need to know.

Am I to say that: "there's always an end for every misery" (underlying meaning = so as happiness) or "good things will never last (in other words = so as bad moments) Both of them are of the same meaning. It's all up to we, our own to choose to see things from which angle. There's no right and wrong between two things, even if they contradict with each other.  I believe that many of us are actually struggling to become a better individual, to lead our life to a brighter future. Nobody wants to get worsen. Somehow, we just don't know which method to use, or even what are the methods exist. That's the reason why people keep trying and keep encountering failures. They do not fail, actually. Every obstacles in life is to help us to grow stronger and tougher. Not to nurture our patience to endure until all problems are ended. They never will. 

However, humans are just too forgetful. Often, they do not remember about their own pasts, about how they've gone through all circumstances and continue their life to this day. If you can do it previously, you must be able to go through it again in future. All this while we are being confined under regulations and limitations. One thing clear is, our memories do not have a limit. We can fill as many things as we like, as long as we want it. And for sure, we can choose not to allocate any spaces for certain stuffs.

It's all up to our own decision. 

*Although we can't choose what situation to be in, we still have the right to decide what to do.
