To be honest now I really don’t know how to describe my mood, the cause of the matter is that my USB cannot be opened again. It seems not as important as we thought, however only I know how significant impact on me. Over the past few years I have done a lot of educational work which completely has nothing to do with what I have learned in the Uni, however those documents fully takes me right back those long sleepless nights I worked my buff off in college to learn English and finance, that's the most valuable and memorable period of all time in my life for ever until I still remember that bittersweet feeling. Those files are indispensable to my life like photos and archived emails that I will never delete on my phone. I like the career I chose, and I also hope that those precious memories will be preserved forever.
