昨天晚上我的一个同学抓住我说：“你记不记得你在英语课上表演过的那个魔术。能不能教教我？”这句话提醒了我，我还是个魔术师。
我一直对于我的魔术师身份感到自豪。注意我的用词“魔术师”，而不是“魔术爱好者”。因为一个真正的魔术师会有自己的风格，自己的原创以及新的魔术套路，不像是那些垃圾魔术爱好者，只会copy大师的杰作。真的，只有天赋卓越的魔术师才能创造或者改进魔术流程。而我就是那么做的。魔术是一门需要智慧和热情的表演艺术，而不仅仅是手法和技巧。
我似乎有很长时间没有表演魔术了。（因为我很忙？）最后我找到了原因，因为我的爱好太多了。看看：开源、自由跑步、网球、书法，等等。（“等等”的意思是我想保留一些信息，让大家永远看不透我^_^）说这些是想表明我喜欢自由的东西。而对于“自由”，我是指自由，而不是指免费。（因为英语里的"free"有歧义，MD，还是汉语好）开源，也叫自由软件；自由跑步，名字已经在那儿了；网球，本质上是自由运动；书法，自由随意书写。
这就是我为什么喜欢物理学的家伙多于计算机学的家伙，因为前者仍在追逐自由，而后者基本已经被这个物质社会腐蚀了。我计算机系的朋友们千万不要对号入座。事实上如果你是我的朋友，那是因为你很被我欣赏。我想说的是， 大多数物理工作者都有这种幻想：更好的认知这个世界。然而我们信息学工作者经常这样想：赚更多的钱。当然了，没有人会对钱说不。但是这个世界对钱过于敏感，很多人没有意识到自己是在用自由、梦想以及更加重要的东西在买钱，因为他们认为钱可以买一切。
然而，信不信由你，我并不认为追逐金钱是一件很恶劣的事情，因为至少那些人是有奔头的。而有些人已经开始慢慢失去他们的热情和梦想，即使梦想的是钱。我周围的有些人甚至开始认为自己去开创事业太老了，并且开始寄希望于下一代。我靠，我们才30不到啊！如果下一代还没有长大就世界末日了怎么办？！
我的一些密友知道我的工作环境很不好。（不知道该怎么说，“没希望？”）但是我永不放弃，因为我热爱CS。我会把每个障碍当作是垫脚石。曾经有人告诉我不要让爱好成为职业，因为那是一场灾难。我现在觉得这是放P，那是因为你没有从内心喜欢它。没有人能相信，在我写BLOG或者在我和朋友网上聊天的时候，我经常有一个我自己写的程序在后台或者另一台机子上运行呢！
好了，我想我已经离题太远。总结一下，自由，热情和梦想是我这篇文章想强调的主题。另外，作为一个完整的故事，还记得那个找我教他魔术的家伙么？对了。我打赌他学这个是为了泡MM，而且我猜对了。我告诉他这个魔术是泡不了女生的，于是我就教他了另一个名为“幽灵卡片”的魔术。上帝保佑他有好运！

Yesterday evening, one of my classmate grabed my arm and asked me:" Hey, remember the magic you played on our English class. Could you teach me?" That reminds me I'm still a magician. I'm always proud of the magician identity of me. Notice the exact word I use here "magician", not "magic amateur". Not like a lousy amateur, who only knows copying real magicians' works, a real magician will create his own style and his own original works, and always try to create new routines of magic show. And believe me, only a talented magician can create or improve magic routines. Those are what exactly I've ever done. Magic is an art of acting, which needs wisdom and passion, not just a sleight of heads or tricks.
It seems a long time since the last time I played magic. (Because I'm busy?) Finally, I figured the reason out, I have too many hobbies! Check this out: open source, free running, tennis, calligraphy, etc. ("etc." means something I want to hold back to myself, then no one can look through me ^_^) So far, I just want to give the point that I love free things. by Free, I mean freedom, not free of charge. Open source, is also known as free software; free running, the name has it; tennis, basically is a free sport; calligraphy, is free handwritting.
That's why I prefer physics guys than computer science guys, because the former are still persuing their own freedom, but the latter are basically corrupted by this material realistic world. Don't any CS friends of mine take my words personally. Actually if you are a friend of mine, that means you are at least someone I really appreciate. What I want to say is, most of physics research workers have this fantasy in their head: Know this world better. Meanwhile, we CS workers' dreams are always: Earn more money. Admittedly, no one would say no to money. But this world is too allergic to money that most people don't even realise that they are using their freedom, dreams, and something more important to buy money, because they believe they can buy everything with money.
However, believe or not, I don't think persuing money is one very bad thing, because at least you got some goal to move forward to. There exists someone slowly lacking their passions and dreams, even for money. Someone aroud me even start to think himself too old to start a career, and start to pin his hope on the next generation. We are all below 30 for God's sake! And what if the world ends before the next generation grows up?!
Some of my intimate friends know that my working environment is not comfortable (I don't know the exact word to put this. "hopeful?") at all. But I never give up, because I love CS. And I take every snag in my way as a stepping-stone. Someone told me that never make your hobby become career, because it is a disaster when that happens. I think it's bullshit, that happens only because deep down you don't truely love it. And you will never gonna believe this, I always got a program written by myself running background or on another machine, when I am writing a BLOG, or I'am chatting with my friends.
OK, I think I've strayed from the point way too far. In sum, freedom, passion, and dream are the themes of this article I want to emphasize. And, as a complete story, remember the guy who ask me to teach him magic? yeah...I bet he want to learn that magic to nail a girl, and I'm right! I told him the magic is not very suitable to win a girl's heart, so I teach him another one called "Ghost Card". God bless him good luck!
