It took me a long time and a lot of hard work but I finally returned to the University of Texas in the fall of 1983 -- a year and a half after almost dying. The next few years were very difficult for me, but I truly believe that in order to see beauty in life you have to experience some unpleasantness. Maybe I have experienced too much unpleasantness, 但我有一个信念——充实地过每一天，尽力做到最好。

单词提示：
Texas n. 得克萨斯(美国州名) ; unpleasantness n. 不幸

答案：but I believe in living each day to the fullest, and doing the very best I can.
本句节选自《My Miraculous Life》

1.信念一词可以说成faith,belief，其中faith表达的信心更强烈一些。
2.充实地过第一天，有些沪友用fully enjoy every day，表达的比较好。
2.do the very best——尽最大努力，这是一种表达很常用。
