2011.02.22: Another year has passed in the blink of an eye, and I realize it's been a long time since I left any warm words here. In 2011, I hope to write more personal things here. A word of warning: from now on, if you don't like it, don't read it! As mentioned in the subtitle, let this blog return to its essence and its original intent. Looking back on last year, I feel more and more that this personal blog isn't personal enough. Many truly personal things never got written here; instead, I posted a few articles and videos that won't stand the test of time. I was afraid of this and that. If I wrote something too simple, I feared someone would look down on it; if I wrote something based on my own understanding, I feared someone with a different cultural background would take exception to it; if I wrote something slightly technical, I feared people wouldn't understand it. In the end, I ended up neither daring to write nor thinking it worth writing.
