"You know what that reflects?" Unsatisfied lives. Unfufilled lives. Lives that haven't found meaning. Because if you found meaning in your life, you don't want to go back. You want to go forward. You want to see more, do more. You can't wait until sixty-five.

ps：每天學(xué)習(xí)都會(huì)有進(jìn)步、有收獲，只是，年紀(jì)大了，東西總是忘，并且，學(xué)習(xí)，真的好像自己一個(gè)人在黑屋子里，聽(tīng)不到聲音、看不到光亮，自己想鑿穿無(wú)盡的黑暗，卻不知道自己能否能堅(jiān)持到墻破的那一刻，抑或，自己也不知道自己鑿的地方是否會(huì)有光明，悲！但，真的猛士，敢于面對(duì)這種絕望和挫折，擦干身上的血汗，繼續(xù)前行！
