问题不在于你的weaknesse，而在于你是否有self-confidence and maturity。
曾经有个很成功的人士（美国人），有人问他有什么缺点，你猜人家说什么？我不擅于选择最好的团队！大概就是这个意思，这位老兄已经一把年纪了，而且是个成功人士。看到了吧，不能说一个人有缺点/弱点，就没有机会成功和成为成功的管理者。首先，一个人要有勇气承认和面对自己的weaknesse。
I think the main point to not about what your weakness is, but how you improve yourself and conquer your problem. The MBA admission is trying to evaluate your maturity, your business savvy, your self awareness and what steps you take to improve yourself and turn weakness around. You shouldn't put too much focus on explaining or cover up your weakness. Your focus is what effort you make to improve yourself. You can definitely say a true weakness in this case, for example, you can say you are not good at English, however, make sure to use examples to demonstrate that you took extra steps in life to learn and self improve your English skills. But everyone's case is different, so you have to write your own story. That also makes the story appear more believable to the audience.
But make sure you don't say weakness that has severe personal flaw. For example, do not say you are lacking business ethic or you are a selfish person...etc. Because these things would make you leave a very bad first impression to the admission. No matter how hard you try to convince your MBA admission officer, they would think you are not suitable to their program and lack of judgement.
Weakness 是个比较Tricky的question, 所以很多人都会写那种擦边球的weakness. 比较：
too detail oriented; get my hands on too many tasks 等等。这些weakness 比较safe，
但是有比较俗套。
就象ziye210说的那样，其实可以把自己的弱点说出来。写得时候可以说有的时候，会有人说
我有＊＊的缺点，我意识到这是缺点，已经怎么样在改进了。当然你也可以Defend你自己，说
这个缺点有的时候也回serve you well.
我当时在准备的时候，就对我自己的情况，挑了个比较不一样的弱点写，我说I was told
that i could talk too much sometimes.
然后写，在中国的culture 环境里，这是比较blunt的。所以，当我了解别人对我有这样的看
法后，我在改进，让自己成为一个good listener. 三思而后言。
然后我又 defend myself，说 the reason i talk a lot is because I'm not afraid of
expressing my views. (在美国人眼中，敢说并不是件坏事)，
最后，又说，besides, being talkative makes me a very social person, which helps me
