"你并不是只属于你自己的
这世上没有任何东西是只属于自己的
每个人总是会和他人相关，
共有着某些东西 所以，
无法自由随意 但也正因为如此 生活才有趣，
才悲伤，才如此惹人爱怜" - xxxHolic

A few years ago, I read that from a comic book.
At that time, I didn't think too much of it.
But now, when I read it again, it gives it a whole different meaning.
You would think if it's yours, it wouldn't affect others.
You should be able to freely do what ever that is supposedly yours.
But in fact, that's just some kind of illusion you've been living in.
Every thing is connected someway or another.
You will never be totally free of doing what you want to do.
But true, as the phrase also rightly points out.
Life is interesting, sad, lovable because of this.
That is also how we are connected to each other.
And we will never be totally alone...
