A journey is a person in itself; no two are alike. And all plans, safeguards, policing, and coercion are fruitless. We find after years of struggle that we do not take a trip; a trip takes us.
把守外海不如把守海口，把守海口不如把守内海。
The question is not whether the thing exists， but whether it has any essence which is capable of existence without us.
Don't wait for the perfect moment, take the moment and make it perfect.
