世上无难事，只怕有心人。中国人常说“有志者事竟成”，意思是只要肯下决心去做，世界上没有什么办不到的事情，困难总是可以克服的。这句话与英文习语“where there's a will, there's a way”意思相同，表示“If one is motivated enough to do something, they will find a way to do it”。
Don't tell me it's impossible. Where there's a will, there's a way. And we're going to find that way.
I have no doubt that Bob will find a publisher for his novel. Where there's a will, there's a way.
