It's been a pleasant year when I look back at the end of 2013. I am still glad that I made the choice of transferring to Lexington so that I could live a normal PhD student life. I paid my dues and now it's time to finish what’s left there in 2014. 2014 will be more crucial if not as crucial. Of course, there are many things I wish I could have done this year, but I guess given the specific circumstance I did my best. Thanks to many things that happened in 2013, I could focus more on what needs to be done next. Happy New Year!
