It would be unwise for one to put everything he cares in a box and carries it throughout his life. It would also be juvenile to leave the box empty, or simply put everything out to ease his way out of the journey. From my perspective, in certain periods of life, one has to appreciate the importance of taking in and letting go. Hence, that procedure of selection matters to me most.

It is not an easy quest seeking the real value of one's life. There were times when I decided to fill up my box with general beliefs collected from the society, considering it is wise to follow the lead of all bright minds. Then I realized all I have was a handful of dogmatic, which varied in perspectives and information. Yet it came the moment I tried to embrace all the emotions, all the feelings, to gain a sense of love and existence. But emotions triggered by chemical components, so it frightens me by the ideas of treasuring such exchange of mere substances. Back and forth, everyone must have stumbled on the real value of money. Would it be the equivalent exchange for happiness? Or would it be a shame to dispute the true powerful effect of such liquid? If so, what distinguished mankind from the animal in our quest to benefit ourselves?

I believe the answer relies on knowledge. It is the most substantial component in the process of selection. By making decisions that supported by righteous self-knowing and justified reasons, one releases himself from the tiresome cell made of imperfections. I experienced that sanguine feeling, when I chose to pursue my studies in the Information Technology oriented class. I am informed of the obstacles, and acknowledged the intense time of a gifted class. However, after all the evaluations, I recognized my original affection for this science itself. So there it was in my box, still sparkling to this day, my profound feeling for computer and technology.

By making reasonable choices, I find my life worthy and meaningful.

It would be unwise for one to put everything he cares for in a box and carry it throughout his life. It would also be juvenile to leave the box empty, or simply to keep everything out... There were times when I decided to fill up my box with general beliefs I collected from the of society,... Then I realized all I have was a handful of dogmatic(dogmatic is an adj not a noun) .... But emotions are triggered by chemical components so i am frightened by the ideas of treasuring such exchange of mere substances... By making decisions that are supported.... I am informed(you should probably use a word like "aware" which fits better) of the obstacles, and acknowledge the intense time of a gifted class. i really like your ideas. Good Luck! Could you please look over mine also?

"all the emotions, all the feelings " repetitiveness
your answer is unclear...is the selection process what matters most or the actual choices in general what matter most, its just unclear. but very interesting i never would think of that!
