……Therefore, I put everything else aside and continued my experiments for the past ten years. Piling, covering, clearing, polishing, I had gotten whatever undesirable every single time, till my anticipation slowly evolved from the sadness of trials and errors into the pleasures of toiling.

I comforted myself by believing that the magnificence of thinking and hard working will eventually lead to knowing the unknown. I am not a gambler, but I bet you that I can strike some luck in what I do.
